Ominous Sphinx

Cycling decks have always wanted their card-filtering to pull double weight, and this is a pointed answer to that wish: a flying body that converts every discard and every cycle into a combat liability for the other side. The -2/-0 is a quiet but deliberate choice. It does not kill anything outright, but it neuters attackers and shrinks blockers, and because it triggers on each individual cycle or discard, a deck built to churn through its hand can stack the shrink on a single creature or spread it across a board. A deck already cycling every turn pays nothing extra for the trigger, so the floor is a 4/4 flier and the ceiling is a recurring tax on whatever your opponent is trying to attack or block with. Note the asymmetry baked into the direction it bends, -2/-0 rather than -2/-2, which keeps the effect honest as a defensive and tempo tool rather than a removal engine. You can stunt a 5/5 into a 3/5 every time you crack a cycling land, but you have to commit to actually doing it. That dependence on a fully built discard-and-cycle shell is what keeps the card from drifting into generic value-flier territory; outside a deck that respects its trigger, it is just a five-mana evasive beater.
