Block + area damage is a combo we don't see very often. The small value of the Doom effect means this is dependent on other Doom sources to be particularly useful.
Deal 7 damage. Apply any debuffs on the enemy to ALL other enemies.
Summon 5. Whenever Osty loses HP, ALL enemies lose that much HP as well.
Gain 5 Block. Apply 7 Doom to ALL enemies.
Gain. Draw 2 cards. At the start of your turn, apply 3 Doom to yourself.
Apply 10 Doom, plus an additional 5 Doom for every 10 Doom already on this enemy.
