Scourge of Fleets
Most board wipes ask nothing of your deck; this one is a contract written against your own manabase. The bounce caps at the number of Islands you control, which means the effect is only as wide as your willingness to play Islands and nothing else. Run a handful and you clear the chaff: a sweep that misses the dangerous fatties is a half-measure. Flood your manabase with Islands (basics, dual lands with the Island type, anything that carries the subtype) and the toughness ceiling climbs high enough to scoop nearly everything your opponents have committed, hand back to owner, no exile, no death triggers, just a full reset to their grip while a 6/6 lands ready to swing. The bounce-versus-destroy distinction is the whole strategic axis: returning to hand spares them the graveyard but also denies any of the sacrifice-payoff or recursion value a wrath would hand them, and it buys you one swing of tempo while they re-spend their mana. The design logic is older than most mono-color payoffs: tie a splashy effect to a land subtype count and you force a builder to choose between consistency and reach. Pay the full price in Islands and the reach is enormous; hedge your mana and the Kraken arrives as a seven-mana 6/6 with a shrug attached.
