OP-16 Garp Deck Guide: Sengoku Navy Build and Tier Placement

OP-16 Garp deck guide correction (2026-07-27): a full card-by-card audit found this guide's central mechanic was invented. Monkey D. Garp (OP16-075) is a CHARACTER card in OP-16, not a Leader, so he cannot have a "leader ability" at all. The real Leader driving this deck is Sengoku (OP16-060): Purple, 5 Life, 5000 Power. His real printed ability is [Activate: Main] You may return 8 of your active DON!! cards to your DON!! deck: Play up to 3 {Admiral} type Character cards with different card names from your hand, a DON!!-recycling engine that cheats Admiral Characters into play, not the "3+ Marines reduces cost by 2" condition this guide previously described. Nearly the entire 50-card decklist below that section (Tashigi as a 1-cost condition piece, Helmeppo, Coby, "Garp's Guards," a second "Vice Admiral Tsuru," "Admiral Fujitora," a "Fleet Admiral Sengoku" with a fabricated stat line, and the event cards Garp's Fist / Marine Standard / Hero's Calling / Absolute Justice / Call to Justice) could not be verified against the official OP16 card list and has been removed rather than repeated as fact. Six weeks post-launch, Sengoku has settled at Tier 2 on onepiece.gg's current tier list.

This guide covers the OP16-060OP16-060Shop on TCGplayer Sengoku Navy deck featuring Garp as a key Navy/Marine character.

OP16-075OP16-075Shop on TCGplayer Monkey D. Garp is the Marine hero who punched Whitebeard across Marineford, raised both Roger's son and Dragon's son simultaneously, and never joined the Warlords despite multiple offers. In OP-16 he's a strong support Character, not the deck's leader; Sengoku is the one pulling the strings.

Sengoku's Navy shell is Tier 2 in OP-16. It is not the best deck. It does not pretend to be. What it does is recycle DON!! to cheat Admiral Characters into play ahead of schedule and beat anyone who is not OP16-065OP16-065Shop on TCGplayer Akainu. That is its identity, and it executes it reliably.

TL;DR: Sengoku's OP-16 Navy deck (OP16-060, Purple) returns 8 active DON!! to the DON!! deck to play up to 3 differently-named Admiral Characters from hand, cheating them into play ahead of the normal curve. Garp (OP16-075) is Navy support, not the leader. Six weeks post-launch, the shell sits at Tier 2 on onepiece.gg. An earlier version of this guide described a fabricated "Garp leader ability" and a mostly invented decklist; both have been corrected below using only verified card text.

OP-16 Garp deck guide: quick answer

Sengoku's real ability returns 8 of your active DON!! cards to your DON!! deck to play up to 3 {Admiral} type Characters with different names from hand, in one activation. That lets you deploy multiple high-cost Admirals (Sakazuki, Kuzan, Borsalino) in a single turn once you've built up 8 active DON!!, well ahead of paying their full costs individually. Garp and the Sengoku Character printing (OP16-066) support the board and DON!! economy in the turns before that activation goes off.

Key Takeaways

• Sengoku (OP16-060, Purple, Leader) returns 8 active DON!! to the DON!! deck to play up to 3 differently-named {Admiral} Characters from hand in one activation
• Garp (OP16-075) is Navy support, not the leader; an earlier version of this guide incorrectly gave him a "leader ability"
• Six weeks post-launch, Sengoku has settled at Tier 2 on onepiece.gg's current tier list
• The confirmed real payoff pieces are the Three Admirals: Sakazuki (OP16-065), Kuzan (OP16-063), and Borsalino (OP16-073)
• Tsuru (OP16-067, 1-cost) is a real deck-filtering Navy support card; her ability looks at the top 5 cards for a Navy hit, not "DON!! generation"
• No independently verified full 50-card tournament decklist for this shell was available at the time of this update

How Sengoku's Deck Actually Works

Sengoku's printed leader ability reads: [Activate: Main] You may return 8 of your active DON!! cards to your DON!! deck: Play up to 3 {Admiral} type Character cards with different card names from your hand.

This is a DON!!-recycling cheat-into-play effect, not a cost-reduction condition. You need 8 active DON!! on the field to activate it, at which point you can drop up to 3 different-named Admiral Characters from hand simultaneously, well ahead of what their individual costs would normally allow on that turn.

The supporting cast bridges the early turns and builds toward that DON!! total. Sengoku's Character printing (OP16-066, Purple, 5-cost, 5000 power, +2000 counter, Navy) has an On Play effect that, if your Leader has the {Navy} type, adds up to 2 DON!! cards from your DON!! deck and rests them, then draws 2 and trashes 2, both accelerating toward the 8-DON!! threshold and filtering your hand. Tsuru (OP16-067, Purple, 1-cost, 2000 power, +2000 counter, Navy, Uncommon) looks at the top 5 cards of your deck, may add 1 revealed Navy card to hand, then trashes 1 card from hand, a deck-filtering tool rather than a DON!! generator.

The failure mode is straightforward: without enough active DON!! banked, the leader ability simply isn't available, and Sengoku's Navy shell plays out as a slower midrange deck without its payoff turn. Removal-heavy decks that pressure your board and your DON!! development before you reach 8 active DON!! are this deck's hardest matchups.

Garp provides Marine pressure as a Character within Sengoku's Navy shell.

What's Confirmed Real in This Shell

Correction (2026-07-27): the "Complete Decklist" this section previously listed (Tashigi, Helmeppo, Coby, and "Garp's Guards" as condition fillers; a second "Vice Admiral Tsuru"; "Admiral Fujitora"; a "Fleet Admiral Sengoku" with an 8000-power +1000-all-Marines effect; and the events Garp's Fist, Marine Standard, Hero's Calling, Absolute Justice, and Call to Justice) could not be verified against the official OP16 card list. Fujitora in particular does not fit OP-16's Marineford/Paramount War theme, since he isn't introduced in the story until years after that arc, and OP-16's confirmed Admiral trio is Sakazuki, Kuzan, and Borsalino. No independently sourced, verified 50-card tournament decklist for this shell was available at the time of this update. Rather than publish another unverified list, here is what's confirmed real:

Leader: Sengoku (OP16-060), Purple, 5 Life, 5000 Power. [Activate: Main] Return 8 active DON!! to your DON!! deck: play up to 3 differently-named {Admiral} Character cards from hand.

Confirmed payoffs, the Three Admirals:

• OP16-065OP16-065Shop on TCGplayer Sakazuki (Akainu): the marquee removal-and-pressure Admiral, also OP-16's top Manga Rare chase.
• Kuzan (OP16-063, Super Alt-Art): board-control ice utility.
• Borsalino (OP16-073, Super Alt-Art): speed-themed Admiral utility.

Confirmed support:

• OP16-075OP16-075Shop on TCGplayer Garp (OP16-075): Navy support Character, not a Leader.
• Sengoku (OP16-066), Purple, 5-cost, 5000 power, +2000 counter, Navy: [On Play] If your Leader has the {Navy} type, add up to 2 DON!! from your DON!! deck and rest them, then draw 2 and trash 2 cards from your hand. A DON!! ramp and hand-filter piece, distinct from the Leader printing.
• Tsuru (OP16-067), Purple, 1-cost, 2000 power, +2000 counter, Navy, Uncommon: [On Play] Look at 5 cards from the top of your deck; reveal up to 1 {Navy} card, add it to hand and place the rest at the bottom of your deck in any order. Then trash 1 card from your hand. A deck-filtering tool, not the "DON!! generation" effect an earlier version of this guide described.
• Tashigi (OP16-029) is a confirmed real Navy card in this set; her exact cost, power, and ability text were not independently verified for this update.

Mulligan Strategy

Keep a hand that can develop your Navy board in the first few turns and realistically banks toward 8 active DON!! by the mid-game, since that's what unlocks Sengoku's Admiral-cheat activation. Specific card-by-card mulligan heuristics beyond that general principle were not independently verified for this update and have been removed rather than repeated as unconfirmed fact.

Step-by-Step: Playing the Sengoku Navy Shell

Early turns: develop your Navy board and start generating DON!!, using Tsuru and the Character printing of Sengoku (OP16-066) to filter your hand and ramp DON!! toward the 8-active threshold.

Mid-game: once you have 8 active DON!!, activate Sengoku's leader ability to return them to your DON!! deck and play up to 3 differently-named Admiral Characters from hand in one turn, a significant tempo swing if the opponent hasn't prepared for it.

Late game: press the advantage from the Admirals you've deployed. Specific turn-by-turn timing beyond this general shape was not independently verified for this update.

Matchup Guide

No official Union Arena-style win-rate tracker exists for One Piece TCG at this granularity either; the specific matchup percentages an earlier version of this guide gave (vs. Akainu, Marco, Buggy, and Law) were reasoned from the fabricated cost-reduction mechanic and have been removed rather than replaced with new unverified numbers. In general, decks that pressure your board and DON!! development before you reach 8 active DON!! make Sengoku's payoff turn harder to reach; check current tournament reports and tier lists for up-to-date matchup information.

Budget Build

Prioritize the confirmed core, Sengoku (both printings), the Three Admirals, Garp, and Tsuru, over any unverified support pieces. An earlier version of this section named specific budget swaps ("Garp's Fist," fewer Sengoku copies) built on cards that couldn't be verified; check the One Piece TCG card rarities guide and current TCGPlayer prices before setting a specific budget target for this shell.

Tips for Sengoku Navy Players

Track your active DON!! count toward 8, since that's the real trigger for the leader ability, not a character-count condition. Getting there is a resource-management question, not a board-state one.

The deck's real payoff turn (returning 8 DON!! to play 3 Admirals at once) is a significant tempo swing, but only once. Sequence your DON!! development so you hit that threshold at a point in the game where deploying 3 Admirals actually closes out an advantage, not just refills an empty board.

If your local meta is heavy on removal that can strip your board before you reach 8 active DON!!, this shell will be slower to find its turn. Evaluate accordingly before committing to it for a specific event.

Frequently Asked Questions

What does Sengoku's leader ability actually do? [Activate: Main] Return 8 of your active DON!! cards to your DON!! deck: play up to 3 {Admiral} type Character cards with different card names from your hand. It's a DON!!-recycling effect that cheats multiple Admirals into play, not a cost-reduction condition. An earlier version of this guide incorrectly attributed a "3+ Marines reduces cost" ability to Garp, who is a Character, not a Leader.

Is Garp the leader of this deck? No. Monkey D. Garp (OP16-075) is a Character card. The Leader is Sengoku (OP16-060).

Does this deck need all 8 active DON!! every turn? No, only to activate the leader ability itself. The deck can develop its board normally in earlier turns and doesn't require holding 8 DON!! before doing anything.

Is this deck good at regionals? It's Tier 2 on onepiece.gg's current tier list, six weeks post-launch. It can compete but isn't a top-tier pick; evaluate your expected local meta before committing to it for a specific event.

What is the deck's best sideboard plan? Not independently verified for this update; check current tournament reports and community deck-tech content for up-to-date sideboard guidance.
