Roost of Drakes

Kicker rewards you twice here, and that doubling is the whole design idea. Cast it kicked and you pay for a payoff enchantment plus its first trigger in one motion: the enters-if-kicked clause hands you a Drake the moment the engine lands, so the extra mana never buys a blank turn. From then on every kicked spell you cast adds another flier, converting a mechanic that usually reads as an optional upgrade into a recurring token faucet. What makes it work as a build-around is the demand it places on your spell selection: the engine is only as strong as the kicker density in the deck around it, so it asks you to overload on spells with a paid-up mode rather than splash one or two. The one-mana cast is the tell. Unkicked, it resolves into an inert enchantment doing nothing until you feed it, which is the price for a card that scales without a ceiling once the deck cooperates. This belongs to a family of enchantments that convert an existing keyword into a value stream, the way certain designs turn every landfall event or every lifegain event into a trigger, except the currency here is a choice you make at cast time rather than a passive game event. That distinction matters: the Drakes come on your terms, in the numbers your mana can support, which is both the appeal and the constraint.
