Waterfall Aerialist

A 3/1 flier folds to any single point of damage, which historically made a body like this a nonbet: opponents traded a stray spark or a chump block and moved on. Ward rewrites that math. The removal an opponent was already going to spend now costs two more mana, and against the cheap answers that punish a one-toughness flier (a one-mana burn spell, a targeted ping), that surcharge often eats an entire turn's worth of tempo. The clever part is that Ward attaches the tax to the exact interaction the fragile body invites: opponents want to point removal at a 3/1 that flies, and each time they do, they pay the toll or let the clock keep ticking. It functions less like a keyword and more like a tempo threshold. Note the asymmetry written into the ability: it triggers only on spells and abilities an opponent controls, so your own auras, pumps, and blink effects sail through untaxed. The result is a beater built to be protected and ridden, where the body's fragility is the incentive that makes the Ward matter and the Ward is what keeps the fragile body on the table long enough to close.
