Engulf the Shore

The clever move here is binding the bounce threshold to your own land count rather than fixing it at a number. A symmetrical Evacuation cares nothing about board state; this one scales with how committed your manabase is to Islands, so a heavy mono-blue build sends two- and three-toughness creatures back to hand while leaving anything with higher toughness in place, yours and theirs alike. The line divides purely on toughness against your Island count, which means the asymmetry is something you engineer: run big enough bodies (or fewer, sturdier threats) and your board rides above the wave your opponent's small attackers do not. Stack Islands and the water rises, but the same lands that power it telegraph exactly how high. It reads as a board wipe and plays as a tempo spell, since everything goes to hand rather than the graveyard, which is both its mercy and its limitation: you are buying a turn against a flood of small attackers, not answering them permanently, and the recast bill lands back on the affected player's side as often as it stalls them. Instant timing is where it earns its slot, letting you hold until a swarm has committed to an alpha strike before sending it all home, ideally with the Island count tuned high enough that nothing relevant survives. A bounce sweeper you size with your land choices is a narrower thing than a flat one, but the player who leans all the way into Islands gets a one-sided reset out of a symmetric template.
