That Green passive looks deadly. When champed she does 135 per special tile (either team) every turn as passive damage. So at 10 tiles that’s 1350 and 20 tiles that’s 2700 a turn.
As mentioned above, when paired with Cardusa she will be devastating since the board will flood with tiles.
She might even make a solid partner to Grocket/Juggs in PvE over Gamora since she will deal 945 a turn (7x135 + presumably the strike tile values on top of that so likely 1500+) and every time you match one of your own strikes she will create 2 more for you adding to her damage. Plus her Blue provides a handy stun like Gamoras does.
