Hurkyl's Final Meditation

The clause that carries the whole design is the two words riding shotgun on the bounce: "End the turn." A full-board return to hand is a familiar blue reset, but ending the turn on top of it is the crueler half. Everything nonland goes back to owners' hands, the stack empties, temporary effects fall off, and the current turn simply stops. Because the surcharge makes casting it during someone else's turn cost three more, the card is built to be fired on your own turn, and that framing resolves what it actually punishes: not a swing already declared, but an opponent's committed board waiting to attack you next. You reset the field on your turn, then end that turn immediately, so their untapped-and-ready side of the table gets scooped back into hand with no combat to spend it on and no stack left to respond with. The tax exists to stop you from holding this up cheaply as a reactive blowout mid-combat; at full cost on your turn it is a clean sweep that returns permanents rather than killing them, which matters against decks that would rather see their threats in the graveyard than back in hand. The rider cuts both ways, since ending the turn ends yours too, which is why this wants to be the last meaningful thing you do: a hard stop, not a setup for anything after it.
