Dormant Gomazoa

A 5/5 flyer for three mana should never come clean, and the encumbrance here is unusually clever: this is a body that can only do anything when someone else acts on you directly. It enters tapped, never untaps on schedule, and so by default it sits inert, a sleeping giant occupying a slot, neither attacking nor blocking. The wake-up condition keys off something the controller normally dreads: becoming the target of a spell yourself. Not your permanents, you. The classic trigger is an opponent's burn aimed at your face or a discard spell pointed at your hand, the kind of interaction a player happily directs at you when you look defenseless. Because the untap fires when you become the target, the Jellyfish stirs while that spell is still on the stack: it stands up before the burn or discard resolves, ready to block on the swing back or attack for five once the coast clears. The structure inverts the usual relationship between you and your opponent's removal, turning their attempt to interact with you into the switch that arms your biggest creature. You can also prime it deliberately with self-targeting spells that name your own face, cantrips and lifegain that point at you, converting the untap clause into a repeatable on-switch. The whole design pays for an enormous body with positional inertia rather than mana, and asks you to spend your own targetability, not a color splash, as the currency.
