The most exciting deck in UNION ARENA: Sword Art Online is the Yellow Goddess deck, focused on the three powerful goddess characters in SAO’s third season: Leafa, Sinon, and Asuna. Of the three, Asuna is the strongest and also the main character of this deck.

Below, we’ll be taking a look at my custom deck build and going over how you can pilot this deck to victory at your next store tournament.

Yellow Goddess Deck key cards

Asuna (Stacia, the Goddess of Creation)

As mentioned above, Asuna is the backbone of this deck, and her strongest version is her raid. Asuna has a very unique When Played effect that makes her highly effective in the current meta. Essentially, you use her to swap one of your opponent’s strongest characters on the front line with a weaker character on the energy line. They both get switched to resting which opens up a huge hole in their defenses. The best part is, however, if you have four life or less you are able to force them to not move the following turn.

This is an excellent way to lock down a really strong character on your opponent’s front line – such as a 10000 BP Saitama or a 5000 BP Lancelot – and preventing them from being used in combat the following turn.

Sinon (Sun Goddess, Solus)

While Asuna acts as a powerful tool to create openings in your opponent’s defenses, Sinon is your late game powerhouse capable of removal via Snipe and Impact. The only problem with this Sinon raid is that you really aren’t going to want to use her until you have at least four life or less, limiting her usefulness early game.

Get to two life or less and she becomes incredibly effective, gaining 500 BP, Snipe and Impact.

Use three-cost Asuna to drain you own life and gain resources

While this Yellow Goddess deck is not at all afraid of taking hits to life, you can accelerate the rate at which you reach four or less by playing a few key cards. One of them is this three-cost Asuna card. She lets you add a card from your life to your hand and draw a card. Because the card added to your hand from your life in this way becomes part of your hand, you can essentially think of this “When Played” as an effect that lets you draw two cards – a very rare ability in UA in general and quite effective.

While normally adding a card from your life to your hand might be seen as a disadvantage, your strongest characters (listed above) gain tremendous power from having less life in your pool, making this card jus straight-up deadly.

As if that weren’t enough, Asuna also has:

3000 BP
Two energy generation
Yellow Color Trigger

She is an absolute must as a four-of in deck.

Leafa (Earth Goddess, Terraria)

While the other two goddesses that make up this deck are primarily offensive characters, Leafa is your defensive line. Indeed, she may just be one of the single most effective Raidless characters in the game up to this point.

Four energy cost makes her easy to play.
4000 base BP makes her an excellent attacker.
Nullify Impact helps defend your life late game.
Activer Trigger is always solid, helping grant additional BP your characters need to survive until the next turn.

While all of these base stats are insane enough, it gets better. Leafa’s When Played enables her to gain 6000 BP and prevents her from being chosen by your opponent’s abilities. This gives her insane staying power, and ties in with her regenerative abilities in the show that prevent her from being defeated by any enemy.

Play her and you are virtually guaranteed to have her around the following turn to dismantle your opponent with.

Situationally effective cards

In addition to the above key cards, this deck offers unique strategies that can be very effective in certain situations. First, let’s talk about a card that stands out as one-of-a-kind and that is this one: Unlimited Landscape Manipulation Ability.

Unlimited Landscape Manipulation Ability

While the first effect listed above is essentially the same effect as raid Asuna (minus the “can’t move” buff you get at 4 cards or less, the second effect is pretty insane, letting you straight-up remove a site from play. This can be an excellent tech to stop powerful cards like Malevolent Shrine from being used against you.

Two-cost Sinon Goddess

The other card that you’ll want to watch for is this pretty insane, two-cost Sinon character. Simply sideline a card from your hand and she gains Snipe that can be used against any character with less than 2500 BP. While that certainly limits the effectiveness of this Snipe effect, it’s still a great way to gain removal against lower BP blockers, forcing your opponent into situations where they have to instead block with their higher BP characters.

From where I’m standing right now, Sword Art Online’s Yellow Asuna Goddess deck is looking like the strongest Sword Art Online deck. It has effective matchups against Yellow Saitama and Blue JJK thanks to the character lockdown and site removal. Meanwhile it should fair reasonably well against other powerhouse decks, with the only weakness being its reliance on having less life in your pool.

To defend against this you’ll need to prioritize having a few Nullify Impact characters around.

In the end, Yellow Goddesses is a fun, and powerful deck with incredible closing moves that could catapult its way to the top of the UNION ARENA meta.
