Dracoplasm

A two-mana flyer that arrives as a 0/0 and reconstitutes itself out of a board you already paid for. The design idea is a clean piece of stat laundering: it converts the power and toughness of creatures that have outlived their usefulness (chump blockers, exhausted utility bodies, things about to die anyway) into a single evasive threat, collapsing a sacrificed pile onto one flier. The discipline is in the entry timing: the sacrifice happens once, as the creature enters, not as a repeatable engine, so the payoff is front-loaded and singular. You are spending a board, not borrowing one. That same timing is the trap, since with nothing to convert the card is a 0/0 that never connects, and a single removal spell pointed at it cashes out the entire sacrifice in one answer. The repeatable pump exists to nudge the math, letting you push a marginal flier toward lethal on a turn where you have red to burn, but it cannot rescue an empty battlefield. It belongs to Tempest's run of shapeshifters that defined themselves by other creatures rather than by a fixed body, and it remains one of the more literal expressions of that theme: a printed 0/0 whose final stats are a sum rather than a number, its ceiling set by exactly how much standing board you are prepared to spend on it.
