Fire Nation Engineer

Raid designs usually pay off the swing itself: a bonus that fires when the creature enters the fray, front-loading the reward. This one inverts the timing, dropping its counter at the end step and only after an attack has already happened. That end-of-turn placement is the whole reason it works as a builder rather than a finisher. Because the counter lands after combat, it never inflates the current attack; it stages the next one, planting a permanent bump on whichever creature or Vehicle is best positioned to carry it. And the target is "another" body, so the Engineer refuses to feed itself, forcing the counter outward onto the board you actually want to grow. The condition is soft on purpose: you need to have attacked, but not with the Engineer specifically, so a 2/3 that would rather block can sit back on defense while your real threats commit to combat and still collect the reward. What emerges is a slow, cumulative aggression tax on the opponent, one counter per turn, permanent, aimed at a Vehicle crew or an evasive attacker that turns each increment into extra damage. It is a modest body attached to a compounding engine, and the design bet is that a board which keeps attacking will outscale one that trades one-for-one, so long as you can keep the raid trigger honest turn after turn.
