Union Arena InuYasha: Complete Set Guide - quick answer

Union Arena's InuYasha set brings the classic feudal Japan demon-slaying anime into the card game with a mechanic that fits the source material perfectly: Jewel Shard counters that accumulate and spend for power effects.

InuYasha works differently from most Union Arena IPs. Where Bleach decks rush power units and JJK decks chain technique effects, InuYasha rewards patience. You build Jewel Shard counters across multiple turns, then spend them through Kagome's Purification for a swing turn that the opponent cannot answer.

There are three distinct ways to build the deck. Each rewards different play styles and budget levels.

How the Jewel Shard Mechanic Works

This is the core of every InuYasha deck. Get it wrong and no archetype functions correctly.

Accumulation phase: Specific InuYasha characters gain Jewel Shard counters when they enter play, when you attack with them, or when specific conditions are met. You cannot rush this. Counter accumulation is paced by the game design.

Spending phase: Kagome's Purification lets you spend counters from any of your characters for a triggered effect. The effect scales with how many counters you spend: fewer counters for small effects (draw 1, power +500), more counters for large effects (draw 3, power +2000, or a condition for Full Demon InuYasha to activate).

Full Demon InuYasha: At maximum counter saturation (4 Jewel Shards on InuYasha), UA50BT-046UA50BT-046 Full Demon InuYasha can enter play as an upgrade on the existing InuYasha. This is the win condition the deck is built around.

Critical rule: You cannot rush Jewel Shards by paying for them directly. They accumulate through game actions. The Counter Rush archetype maximizes the speed of accumulation by flooding low-cost characters. Control archetypes accept slower counter buildup in exchange for defensive tools.

Archetype 1: Counter Rush

Recommended for: Beginners and budget players. Lowest complexity of the three archetypes.

Core strategy: Play as many low-cost Jewel Shard characters as possible in turns 1-3. Each one adds a counter to your pool. By turn 3, Kagome can spend 2-3 counters for a draw burst or power boost that overwhelms the opponent's defense.

Key cards:

• Low-cost InuYasha crew characters (1-2 BP): Stack them fast
• Miroku (4x): UA50BT-068UA50BT-068 Miroku appears in the UA starter deck at 4 copies. He generates Jewel Shard counters efficiently and is budget-accessible
• Kagome (Rare, $6-10): The engine. You need 3-4 copies. Without Kagome, the counter spend phase does not function
• Base InuYasha (Rare): UA50BT-042UA50BT-042 The counter accumulator. Runs 3-4 copies alongside Miroku

Turn pattern:

• Turn 1: 1-cost crew, add first Jewel Shard
• Turn 2: 2-cost character, second Jewel Shard
• Turn 3: Kagome enters. Spend 2 counters for draw boost. Attack for BP advantage
• Turn 4-5: If base InuYasha has 4 counters, Full Demon InuYasha activates. Close the game

Budget cost: $40-60. Miroku from the starter deck, budget Kagome copies, low-cost crew reprints. Full Demon InuYasha SR is not required for this archetype to function, though it is the ideal top end.

Weakness: Vulnerable to opponent removal on Kagome. If Kagome gets removed before you spend counters, the burst turn does not happen.

Counter Rush archetype: low-cost Jewel Shard characters flood the board in turns 1-3, with Kagome spending counters for the burst swing.

Archetype 2: Sesshomaru Control

Recommended for: Experienced UA players. Harder to pilot than Counter Rush.

Core strategy: Accept a slower early game. Use Sesshomaru and Kikyo as high-cost defensive pieces while InuYasha builds counters in the background. Win by attrition rather than speed.

Key cards:

• Sesshomaru (high-cost): UA50BT-004UA50BT-004 The defensive anchor. His power threshold denies opponent attacks. Runs 2-3 copies
• Kikyo: UA50BT-048UA50BT-048 Provides a second high-power blocker. Thematically Kagome's past-life rival, mechanically a defensive complement
• Naraku (1-2 copies): UA50BT-025UA50BT-025 Disruption splash. Naraku's effect taxes the opponent's resources while you build up
• Full Demon InuYasha SR: More important in this archetype as the singular win condition when the board stalls

Turn pattern:

• Turns 1-4: Defensive posture. Block attacks with Sesshomaru and Kikyo. Let InuYasha accumulate counters passively
• Turns 4-6: Kagome spends 3-4 counters for maximum effect. Full Demon InuYasha enters
• Turns 6-8: Sesshomaru plus Full Demon InuYasha is an unanswerable two-card combination

Budget cost: $90-140. Sesshomaru and Kikyo are higher-rarity pulls. Full Demon InuYasha is nearly mandatory in this build.

Weakness: Extremely slow opener. Faster decks (Bleach aggro, JJK technique chains) pressure you before Sesshomaru arrives. You must decide early whether to block or let Life cards flip.

Sesshomaru Control archetype: high-cost Characters arrive in turns 4-6 after the counter engine is established, creating an unanswerable board state.

Archetype 3: Naraku Disruption

Recommended for: Players who enjoy denying the opponent's game plan.

Core strategy: Use Naraku's ability to disrupt the opponent's hand, remove their key pieces, or deny their own counter mechanics (valuable in UA mirror matches). InuYasha builds counters in the background while Naraku taxes every opponent action.

Key cards:

• Naraku: The deck's namesake piece. His effect likely costs BP or Action Points to use, so timing is critical
• Inuyasha/Kagome/Miroku: Same base engine as Counter Rush but run fewer copies to make room for Naraku support
• Disruption Event cards: UA event cards that disrupt opponent plays

Warning: This archetype has the least JP data supporting it. Counter Rush and Sesshomaru Control are the established builds. Naraku Disruption is theorycrafted from the available card descriptions. Test before investing.

Competitive Verdict

JP tournament data (8 weeks of regional events): 52-55% win rate puts InuYasha at mid-tier competitive. Not the dominant force, but solidly above the 50% line. The deck can win regionals. It is not the consensus best deck in the UA EN meta.

EN meta shift: EN playerbase tends to favor aggro in the first weeks of a new IP release. If the EN community skews aggressive, Sesshomaru Control gains value. If EN mirrors Counter Rush, the deck-on-deck matchup data may shift.

Who should build InuYasha:

• Players who enjoy the anime (theme resonance matters for play enjoyment)
• Players who want a mid-tier deck with a clear skill ceiling
• Players looking for a less-played IP than Bleach or JJK in the early EN meta

Who should wait:

• Players who want the dominant deck: Wait for post-launch EN data before committing
• Players on tight budget: Counter Rush is affordable; Sesshomaru Control is not

Box EV and Pull Rates

Box contents (130-card set, JP data):

• Booster box: approximately 36 packs
• Full Demon InuYasha SR pull rate: roughly 1 per 2-3 boxes in JP
• Secondary SR cards (Sesshomaru, Kagome alternate art): 1 per box average
• Competitive Rare cards (Kagome, Miroku): 3-5 copies per box average

EN pricing projection:

• Box: $60-70 (street price, estimated 10-20% below JP market)
• Full Demon InuYasha SR: $30-50 EN (JP is $40-60; EN print volume slightly higher)
• Kagome (Rare): $6-10 EN

Box EV: Roughly neutral at JP street price. EN should be similar. Neither a strong value play nor a trap. Buy 1-2 boxes for the play experience; buy singles for competitive builds.
