Hemosymbic Mite

The trigger fires on tapping rather than declaring an attack, and that distinction is what pulls this out of the narrow combat-trick lane a one-drop pumper usually occupies. Anything that taps the body feeds the bonus: a convoke payment, a crew requirement, a tap for mana, a tap-to-activate outlet. That turns a small creature into a repeatable payoff riding on an engine the deck was already running for other reasons, and because the buff lands on a second creature rather than staying home, it sidesteps the usual failing of tiny pump enablers that trade down to the first blocker. The scaling is the part worth building around: X equals the Mite's own power, so every counter or anthem dropped on it does double duty, amplifying the bonus it hands off. Untouched, it grants +1/+1 per tap, modest but not idle; the ceiling is what earns the build-around, since a Mite grown to three or four power passes a real swing to a threat that will actually connect. Holding it in check is the tap requirement itself: on an empty board, or a stalled turn where nothing wants to tap, the ability does nothing. This is a piece designed to anchor a subtheme that treats "becomes tapped" as a resource to spend rather than a cost to dodge, rewarding decks that have already committed to tapping their own creatures on purpose.
