The Best UNION ARENA TCG Decks Right Now (2025)
Looking for the best UNION ARENA deck to take with you to your next store tournament and get your favorite winner card? I’ve compiled a list of the most meta relevant decks right now, starting with the current best decks in the format.
UNION ARENA currently boasts a surprisingly wide array of competitive decks given how new the game is. And while there are many playable decks, the very top of the format is largely being dominated by two decks in particular: Purple Code Geass and Blue Sukuna.
After that, Code Geass Green is performing well at tournaments, and we’re seeing several Yellow JJK decks also cropping up here and there.
Other than that, an oldie but a goodie Kurapika has made a surprising comeback taking multiple top finishes in the latest Egman tournament – a tournament that tends to draw many of the strongest players around to complete for solid prizes.
Lastly, the latest best deck to grace the scene is none other than Yellow Demon Slayer featuring Tanjiro. Of course, new decks tend to see play as players are both excited to try out new mechanics and IPs as well as looking to gain advantage against players who are less versed in countering them.
We’ll get into all of these decks and more below in the current UNION ARENA meta rundown.
#1 Code Geass Purple
1st place Egman tournament by Shawn Brophy
When I first got my hands on Code Geass Purple I was blown away by its potential. This deck’s strongest card is the powerful Guren Mk-II which forces your opponent to block while also granting Impact. That combined with a plethora of powerful BP reduction cards and you have arguably the strongest deck in the format.
Not only is Code Geass a powerhouse, it’s got a strong matchup spread and ways to deal with just about every deck.
Going up against a Kurapika? No problem – drop that BP by 1000 via Gawain or two-cost Lelouch. Need to clear your opponent’s board? No problem: Raid a Guren and force them to block. Really the only drawback of this deck is the fact that you can easily exhaust your energy line if you aren’t careful because of how many five-cost raids you have and the fact that your Special is a two AP cost in hand.
With that being said, Code Geass Purple is a fun, powerful deck that has the tools it needs to stay meta relevant for a long time to come.

#2 Blue Sukuna with Nanami
1st place Bandai Card Game Fest tournament by Robin SwaN
Blue Sukuna Blue Sukuna was a pretty hyped deck even before it came out with the official JJK release, bringing with it a fun new mechanic into the UNION ARENA TCG meta, one that is focused on hunting for specific cards (Sukuna’s Finger) and getting said cards into the sideline.However, it’s morphed over time into an even stronger version of itself – one that uses Nanami to great effect.
As a non Blue Sukuna player, I have to say this is the one deck I fear facing the most. It’s just so good and it only gets stronger as the game progresses. The inclusion of Nanami and the Ratio special is a brilliant choice as Nanami frustrates and slows down your opponent while threatening huge moves if your deck hits that 15 or less number that grants him both Impact and Damage 2. Meanwhile, the Ratio Special is arguably the best one in the game as it denies decks like Purple Bleach fuel to their sideline.
This deck is the one I see most commonly played at store tournaments, and you are likely to either play it or play against it wherever you go in the UA world.

#3 Kurapika Green Hunter x Hunter Deck
2nd place by Jeremy Eggers – Egman Events tournament
This UA heavyweight was once the single strongest deck around. New sets, however, have brought with them powerful strategies to level the playing field. Today, Kurapika is still in contention for best deck but not tier zero as it once was.
You don’t need to look much farther than Kurapika’s Raid card to see why this deck is powerful. A 5000 BP essentially makes Kurapika one of the strongest attackers in the game. And that’s without taking into consideration the other powerful effects it has at its disposal – like Snipe plus Impact.
Kurapika
A solid rung of secondary attackers, plenty of shift targets, and strong draw support make Kurapika currently the deck to beat in the UNION ARENA metagame.
While Kurapika dismantles your opponent’s front line, characters like Neon provide much needed draw support, even enabling you to play a character directly from the top five cards of your deck in the active position.
Meanwhile, many of the characters in this deck have access to the powerful Impact keyword, making it easier to hack away at your opponent’s Life cards.
Kurapika hits hard and has a plethora of useful cards at its disposal that make it a strong deck that’s relatively easy to play.

#4 BLEACH Purple
2nd place at the Bandai Card Games Fest tournament by Christopher Juarez Frajio
BLEACH Purple has been a UA staple since the beginning, and it’s still doing well at tournaments, even managing to take second place at the big Bandai Card Fest tournament. It’s not hard to see why this deck remains popular with players. It’s arguably the most well rounded deck, boasting consistency, power, and a deck filled with characters mostly under five-cost.
If you haven’t played BLEACH Purple yet and are looking to build it, the starter deck is a great pick as it has many of the cards you need to build the complete set. It’s well worth picking up two of these starter decks and then getting the singles for what doesn’t come in the starter decks, like this deck’s strongest card: five-cost Ichigo Kurosaki.
Ichigo Kurosaki (041)
Using his “when played” effect you can sideline virtually anything you face, as long as you have the right amount of cards in your sideline to remove. As if that weren’t enough, you have the powerful Renji backing you up – a character with added removal plus the Damage 2 keyword outside the raid box, making him lethal raided or not.
All of that being said, BLEACH has been dropping out of popularity lately thanks largely to the rising dominance of Blue Sukuna with Nanami. As mentioned above, that build leverages cards that bounce characters to the hand and to the bottom of the deck rather than sidelining them. While having a bad matchup against one deck isn’t a huge deal, it is a big deal when that one deck also happens to be the most popular around.
If we see less Sukuna around in the coming weeks and months, you could also see more BLEACH Purple around, as well at tournaments.

#5 Code Geass Green Lancelot
I’ve played a lot of Lancelot and it’s certainly a deck that’s quite strong – when it works. If you manage to hit your curve, this deck is absolutely deadly and capable of decimating your life in a few turns like none other.
While the Air Cavalry Lancelot is the card that catches your eye the quickest, it’s actually the six-cost Lancelot raid that is this deck’s most reliable card. It’s very easy to hit six energy in a deck so focused on energy generation, and the six-cost Lancelot is an absolute beast complete with Damage two and a “when played effect” that bolsters its BP for an entire turn.
That being said, eight-cost Lancelot is your closer and if you can manage to get two of these onto the field, it’s highly probable you’ll just flat out win. It’s arguably the strongest card in the game right now with a powerful removal effect, damage 2 and Impact, meaning no matter what happens in the battle you’re taking some life.

#6 Demon Slayer Yellow Tanjiro
9th Place Joshua Ravo - Yellow Demon Slayer Tanjiro – Egman Event’s 5X Demon Slayer Win-A-Box
And, finally among the top tier decks we have the new kid on the block: Demon Slayer Yellow with Tanjiro. It will be interesting to see how long this lasts as it could be interest in the brand new set is driving popularity for this deck that otherwise doesn’t actually look the strongest on paper. However, it’s had a solid early start taking top finishes at both the local level and via larger events.
This deck is really all about using the Nezuko Tanjiro sibling combo to move characters in and out of the front line in order to unlock added attacks each turn. Unlike other top tier decks it’s more of a synergistic play rather than relying on one powerful top attacker.
This deck’s main weakness, however, is the same as most of the deck’s in demon slayer and that’s removal. Your only added removal is two AP Tanjiro and he’s only sidelining characters with 3000 BP or less. While you can and should look to combo that with the two-cost Nezuko who can lower BP, it’s a lot of moving parts to get the removal you need. If Tanjiro could sideline 4000 BP characters, this deck would be much scarier.
These are the strongest decks in the game right now you should know about, but stay tuned as I will be updating this list with even more strategies you can use to compete at your next UA store tournament!
