Mischievous Chimera

The engine rewards a habit good Izzet decks already have: keeping mana up to act on the opponent's turn. Where most instant-speed payoffs are self-contained (a counter answers a spell, a burn spell kills a creature), this one adds a rider to the first thing you do each opponent's turn, converting any interaction into a point of reach and a scry. The per-instance reward is tiny, but the tempo cost of collecting it is usually zero, because you were going to hold up that counterspell or removal anyway. What ties the payout to a specific operating style is the timing clause: the trigger only fires on your first spell during an opponent's turn, so it does nothing for a deck that dumps its hand on its own turn and passes. It asks you to run the draw-go posture, to leave windows open, to want the opponent to give you something to respond to. Flying keeps the 2/2 relevant while the chip damage and card selection accrue in the background, turning a reactive shell's normal problem (games that stall while both players hold up mana) into a slow clock and a smoother draw. It is a payoff card that pays out only to a deck genuinely built to hold up interaction, and it makes that plan close faster and dig deeper without ever asking you to change what you were already doing.
