How does Even the Score interact with effects that modify how much attack damage a character takes, such as
Blast Suit.
[Source: WotC]
Even the Score doesn’t directly modify how much attack damage is being done to the character (note it doesn’t use “instead”), so it waits for effects like
Blast Suit to apply, then sees if the character is taking more than enough attack damage to be KO’d.
No. Only damage done by the attacker counts as attack damage. Damage done by other cards, such as the damage done by Even the Score, isn’t attack damage.
