That card's EV is negative in this build — why are you even running it

That card's EV is negative in this build configuration — WHY is it in the deck??

Using the database values: that support card buffs +45 attack, lasting 2 turns. But your main attacker only activates under the opponent's debuff state — the buff window and your activation window don't overlap. You're spending a resource to produce zero incremental damage.

Correct swap: the +DEF defensive card. Survive the opponent's attack wave first, then deploy your high-cost finisher for the comeback. Current build is burning resources inefficiently. This needs to be fixed before the next ranked match.

EV framework for card evaluation is something I'm trying to learn. The floor/ceiling/interactability three-factor model makes it more concrete than other explanations I've read.

The interactability metric is the one most new players skip. A card that can be countered by commonly-played responses is worth less than raw power suggests. Every high-ceiling card has a weakness.
