Thunderclap Drake

Cost reduction on a two-mana flier is old territory, but the sacrifice ability marks this as a spellslinger payoff bolted to one very specific counter: the number of times you've cast your commander from the command zone this game. That number governs how many copies your next spell makes, which ties the ceiling to something most spellslinger tables ignore, since those decks generally want their commander glued to the battlefield as a persistent engine rather than dying and getting recast into the tax. This card rewards the opposite instinct, or at least a shell willing to send its commander back home a few times. The counter is cumulative across the whole game, so the ability is a stored charge rather than a burst: the drake sits shaving a generic mana off your spells until you decide the copy count is worth trading the body. The sequencing is the elegant part. You crack it first, paying its own cost, and it sets up a delayed trigger; the copies then attach automatically to whatever instant or sorcery you cast that turn, no priority games required. Choosing new targets on each copy is the flexible clause, letting one burn or draw spell fan across the board or stack onto a single threat. It is a build-around whose reward scales with a play pattern you have to court deliberately, and it stays a serviceable flier and cost reducer even in a deck that keeps its commander parked.
