Marang River Regent // Coil and Catch

Split cards usually force a permanent choice between two purposes; this one refuses to let the choice cost you anything. The back half, Coil and Catch, is a four-mana instant that draws three, discards one, and then shuffles itself back into your library instead of going to the graveyard. That shuffle is the load-bearing piece: casting the cheap card-selection mode does not spend your six-mana finisher, it recycles it, so the Regent goes right back to being a topdeck you can draw and cast for real later. The two halves stop cannibalizing each other. Reach for gas now, and the flier is still live; hold for the flier, and you have not been sitting on a dead card in the meantime. The front side is a 6/7 flier whose enters-the-battlefield trigger returns up to two other nonland permanents to hand, and the "up to two, any nonland" wording is deliberately loose: it can answer two of an opponent's threats at once, or bounce one of your own permanents to re-trigger an entry effect. It resolves that bounce on your terms, since without flash the body arrives at sorcery speed. Tempo bounce stapled to a large evasive body has historically demanded a premium or committed hard to a single job. Splitting the card is what lets a slower deck justify a six-drop it might otherwise never want to hold: the slot is never dead because either half is always the answer to something.
