Crackling Cyclops

A 0/4 that hits for nothing until you spend a card on it: prowess distilled into its most aggressive form. The 4 toughness does two jobs at once, letting the Cyclops stand in front of early attackers and survive the ground stall while your spells go on the stack, then converting to a 3/4 the moment one is cast, a 6/4 or 9/4 if you chain two or three in a turn. Where prowess grants a stackable +1/+1 that also fattens toughness, this trades width for spike, adding +3/+0 per noncreature spell and leaving the body exposed to burn between combats. The reward is front-loaded onto the attack step, so the play pattern is to hold the wall until you can empty a hand of cantrips and burn into a single lethal swing. It punishes overcommitting to any one trigger (there is no lasting board presence, only a window that closes at end of turn) and favors the spell-dense deck that treats creatures as finishers rather than the plan. The lineage runs through every spells-matter beater that wanted to be more than a 2/1 with prowess: this one keeps the fragile base but promises a much larger payoff for the deck built entirely around casting instants and sorceries.
