Union Arena Attack on Titan Vol.2: New Yellow Color

TL;DR: Attack on Titan Vol.2 (UEX07BT) releases September 18, 2026, at $4.99 per 12-card pack, 73 card types plus 6 Action Point types (28C/25U/12R/8SR). The set introduces Yellow to the Attack on Titan card pool for the first time, headlined by Eren Jaeger (Doomsday Titan), a 13-cost, 8000 BP Yellow Raid Character that cheats Nine Titans affinity cards onto the field. Mikasa Ackermann (Yellow) and Levi (Blue) round out the confirmed SR lineup. No starter deck exists for this release, it's booster-only like the original UE10BT set.

What's new in Union Arena Attack on Titan Vol.2? (quick answer)

A new color. The original Attack on Titan set never printed Yellow cards, so Vol.2 giving the franchise its first Yellow characters is a real structural addition, not just new art on old mechanics. The set also brings Final Season character designs and voice-cast autograph cards to a franchise whose first Union Arena release used earlier-series art.

Eren Jaeger (Doomsday Titan): the set's chase card

Eren Jaeger (Doomsday Titan), UEX07BT/AOT-2-022, is a Yellow SR Raid Character carrying the Rumbling and Inheritor of the Titan affinity tags. His base cost is a steep 13 energy, though it drops by 5 while he's anywhere other than your field if you also control a card with Zeke in its name, a real discount for a deck already running the right support. At 8000 BP, he's far above the format's usual character stat lines.

Eren Jaeger (Doomsday Titan)'s When Played ability cheats a Nine Titans affinity card straight onto the field, and an Activate: Main ability lets you repeat that play for 1 AP later in the game.

His When Played ability plays up to one Nine Titans affinity card from hand or sideline directly onto the field, already set to active. An Activate: Main ability, once per turn and not on the turn he's played, lets you pay 1 AP to trigger that same When Played effect again, meaning a single copy can cheat two Nine Titans pieces into play across a game rather than just one.

Mikasa Ackermann and Levi round out the confirmed SRs

Mikasa Ackermann (UEX07BT/AOT-2-008) is also Yellow, a 4-cost, 4000 BP Character who can't be blocked by anything with 5000 or more BP, and gains Impact once her opponent drops to 1 life. Her When Played ability activates the field, provided you control four or more uniquely-named Yellow characters without the Rumbling affinity, and your opponent is at 5 or less life, a real payoff for a wide, non-Rumbling Yellow board.

Mikasa Ackermann's evasion and late-game activation ability, both built around Yellow's new presence in the Attack on Titan card pool.

Levi (UEX07BT/AOT-2-042) stays in familiar territory, Blue, at 5-cost and 4000+ BP. His When Played draws a card and can sideline a hand card to switch one of your Action Point cards to active. When Attacking, paying 1 AP lets him either draw a card and gain 1000 BP, or gain 1000 BP plus Impact, a flexible attacker that scales with how much AP support you're running.

What's confirmed in the set

Bandai's official UEX07BT product page confirms 73 card types plus 6 Action Point types, split 28 Common, 25 Uncommon, 12 Rare, and 8 Super Rare, smaller than a full numbered booster but consistent with the Vol.2-style releases the franchise line has used before. Packs run $4.99 for 12 cards, 16 packs per display, 16 displays per case.

Collector extras confirmed for this release: foil-stamped autograph cards from the Final Season voice cast (Yuki Kaji as Eren, Yui Ishikawa as Mikasa, Marina Inoue as Armin, Hiroshi Kamiya as Levi, Romi Park as Hange Zoe, and Ayane Sakura as Gabi Braun), newly-drawn illustrations across Eren, Mikasa, Armin, Levi, Hange, Gabi, and Falco Grice, serial-numbered hand-signed Action Point cards at an extremely low pull rate, and 8 box-topper designs (5 foil, 3 silver foil) at 1 per box.

Unlike Re:ZERO, there's no starter deck attached to this release. Vol.2 is booster-only, the same structure the original Attack on Titan set (UE10BT) used, so building a deck here means assembling from packs or singles rather than starting from a ready-made 50-card list.

The post-launch Red comparison is now covered by the Mikasa deck guide, while the combined Re:ZERO and Attack on Titan tier refresh tracks public list repetition separately from Bandai's official results archive. Yellow remains a watchlist package until that evidence changes.
