Perplexing Test

The modality is the whole trick here: a table full of go-wide decks and a table full of fatty ramp piles want opposite halves of this card, and one instant answers whichever board is the threat. Against a token swarm you clear the chaff without touching the nontoken threats that were built to grind through it; against a fistful of expensive nontoken threats you bounce them all back to hand and force the table to recast, mana they will not have twice. What separates it from a straight Cyclonic Rift or Devastation Tide is the surgical exclusion built into each mode: bouncing all nontoken creatures leaves your token engine intact, and bouncing all tokens leaves your hard-cast board standing. Read as a Fog with teeth, it also works as a combat reset at instant speed, bouncing declared attackers back to hand and forcing the attacker to recommit them next turn. The design belongs to a small family of blue mass-bounce effects that reward asymmetry rather than symmetry, punishing the archetype your own deck is not: the token player casts the nontoken mode, the elemental-and-artifact player casts the token mode, and each walks away with their own board mostly untouched.
