Wave Goodbye

A mass bounce that reads the board for +1/+1 counters is a strange filter to hang a sweeper on, but the asymmetry is the whole design. Where a symmetrical Evacuation or Devastation Tide picks up everything you own alongside everything they own, this one lets you keep whatever you have already grown: a creature that entered with a counter, or one you pumped with a modular trigger, an outlast ability, or any of the dozens of counter-generating engines that fill a deck built to abuse it. The counter is not incidental; it is the toll the effect charges for immunity, and it rewards a board state you had to invest turns building rather than one you assembled the same turn. Timing matters too, because it resets tempo without touching the graveyard: enters-the-battlefield creatures go back to be recast, aura-dependent boards collapse, and tokens without counters vanish for good, since a token ceases to exist once it leaves the battlefield. The trap is that it punishes counter decks least and blink or token decks most, so the same card that feels one-sided across the table can read as a blank against the wrong opponent. It sits in a small lineage of blue resets that try to be selective rather than total, and the counter clause is a cleaner selector than the "you control" or "cheapest converted mana cost" riders other bounce sweepers have leaned on.
