Spider-Gwen, Free Spirit

The trigger keys off a verb most looter effects never touch: not attacking, not entering, but becoming tapped. That opens the discard-draw window to any reason a creature taps, and combat is only the most obvious one. Tap to attack, loot; but tap for a mana ability, a convoke cost, a crew requirement, or an activated ability that demands tapping this creature, and the loot fires just the same. It even survives the attack step being denied: an untapper that taps and untaps repeatedly turns one 2/3 into a rummaging engine. The discard is optional and the loot is a wash on card count, which is the restraint that keeps a three-mana body from running away with a game: you filter, you don't accumulate. Reach on a red creature is the quiet second job, giving an aggressive shell a way to hold the ground against fliers without spending a slot on it. What makes the design sit differently from the standard attack-trigger looter is that the trigger doesn't care who taps the creature or why; combat becomes one input among several rather than the whole engine, and any deck happy to tap its own permanents for value gets a second dividend every time it does.
