Frenzied Devils

A five-mana 3/3 with haste reads as underwhelming until the second line reframes what it is: not a creature so much as a payoff bolted to a body. The +2/+2 trigger fires on every noncreature spell you cast, and because it lasts until end of turn, the boosts stack: two spells in a turn make it a 7/7, three make it a 9/9. Haste is the piece that ties the design together, because the whole plan only works the turn you commit the spells, and a summoning-sick attacker would waste the effort. It rewards a hand full of cheap instants and sorceries deployed in a single burst, turning a spell-slinging shell's overflow into combat damage rather than reach. The tension in the card is the sequencing math: you want the devil already on the battlefield when the storm of spells comes down, which pulls against the impulse to spend early turns casting those same cheap spells to develop. It is a finisher for a deck that was already casting a critical mass of noncreature cards and needed a way to convert that velocity into a lethal swing, and it asks you to hold your spells for the turn the attack matters.
