Union Arena Code Geass Deck Guide: Purple Lelouch 2026

TL;DR: Purple Code Geass runs on Lelouch Lamperouge (UE04BT/CGH-1-017, 4-cost, 3500 BP), a Character who can't be blocked by anything with 3500 or more BP, forces the opponent to sideline a hand card When Played, and draws two cards as insurance if he's ever sidelined himself. Kallen Kozuki (UE04BT/CGH-1-003, 1-cost) backs him up, gaining 1000 BP during your turn whenever Lelouch is on the field. UE04BT released December 13, 2024, one of Union Arena's earlier EN sets.

What does the Union Arena Code Geass deck actually do? (quick answer)

Play Lelouch Lamperouge for evasion against most of the format's bigger bodies, strip a card from the opponent's hand on entry, and keep pressuring with Kallen's cheap, scaling body alongside him. It's a tempo-and-disruption deck that punishes an opponent for not having a big enough blocker on the board, rather than a straightforward stat-race plan.

Overview: Lelouch's evasion and hand-disruption engine

Lelouch Lamperouge (UE04BT/CGH-1-017, SR) is a 4-cost Purple Character with 3500 BP and the Order of the Black Knights affinity tag. His printed text carries real evasion built in: he cannot be blocked by a character with 3500 or more BP, which covers a meaningful slice of the format's bigger bodies outright.

His When Played ability adds hand disruption on top of that evasion: your opponent places one card from their hand into their sideline the moment he enters play. And if Lelouch is ever sidelined himself, whether from an opposing removal effect or your own sequencing, his When Sidelined ability draws you two cards, a real insurance policy that softens the cost of losing him.

Lelouch Lamperouge's printed text: evasion against most big blockers, a hand-disruption trigger When Played, and a two-card draw safety net When Sidelined.

Kallen Kozuki: the direct Lelouch synergy piece

Kallen Kozuki (UE04BT/CGH-1-003, R) is a cheap 1-cost Purple Character at 2000+ BP, also carrying the Order of the Black Knights affinity tag that ties her directly to Lelouch. Her During Your Turn ability is straightforward: if Lelouch Lamperouge is on your field, she gains 1000 BP, no additional cost or activation required beyond both cards sharing the board.

That's a real, no-strings payoff for running both pieces together rather than splitting your list across unrelated Purple staples. Her Trigger effect adds further flexibility: playing one purple character card with 2 or less required energy and 1 AP cost from your sideline, set to active onto your front line, a real tempo tool for redeploying a cheap piece you'd already committed to the sideline earlier in the game.

Kallen Kozuki's During Your Turn ability rewards running her alongside Lelouch directly, no activation cost required beyond both being in play.

Step-by-Step: piloting Purple Code Geass

1. Play Lelouch before assuming you need to out-stat the opponent's board. His built-in evasion against 3500+ BP characters means a lot of the format's bigger bodies simply can't answer him in combat.

2. Get Kallen onto the field alongside Lelouch as early as reasonably possible. Her BP boost has no activation cost, so there's no reason to delay pairing them once both are available.

3. Don't panic if Lelouch gets sidelined. His When Sidelined ability draws two cards, so losing him to removal isn't a pure loss, factor that card draw into your follow-up plan rather than treating it as a wasted turn.

4. Use Kallen's sideline-redeploy Trigger to reset tempo, not just to refill the board. Bringing a cheap piece back active can matter more for the extra attacker than for raw card count.

Tips

Read Lelouch's evasion text precisely before assuming it blocks everything. It only stops characters with 3500 or more BP from blocking him, smaller bodies can still trade with him in combat if the opponent chooses to.

Community deck-tech coverage of Union Arena's earlier 2024 launch sets has generally treated Code Geass as a solid, long-running archetype rather than a current headline pick, useful context if you're comparing it against newer franchises with fresher regional results.

That longer track record also means the secondary market for Code Geass singles has had roughly two years to settle. A card like Lelouch's SR print is easier to price confidently than a chase card from a set that launched last month and is still working through launch-week hype, useful context whether you're buying to compete or buying to collect.

If you're building past these two cards, prioritize additional Order of the Black Knights affinity pieces that reward the same board state Kallen already checks for, rather than diluting the list with unrelated Purple staples that don't interact with either card.

Watch your own hand size when Lelouch's When Played ability forces the opponent to sideline a card. Since that effect targets the opponent, it doesn't cost you anything directly, but it's worth tracking how the resulting sideline count on their side changes what they can afford to do on their following turns, especially if their own deck has effects that key off sideline count the way some Union Arena archetypes do.

Where Code Geass actually stands right now

Union Arena's official top-placing decks archive doesn't currently list a headline recent regional result for Purple Lelouch the way it does for several newer archetypes. That's consistent with UE04BT's status as one of the game's earlier December 2024 sets rather than a sign it's stopped being played, older card pools naturally cycle out of recent tracked results even while remaining genuinely playable.
