Temporal Fissure

Welding bounce onto Storm is an odd marriage, and the mismatch is exactly what makes this one dangerous. Single-target return-to-hand at five mana is unglamorous filler; multiply it across a storm count, though, and it stops removing a permanent and starts unwinding a board. Each copy peels another permanent back to its owner's hand, and once the count climbs high enough you are sending an entire battlefield home in one cast, leaving the opponent to replay lands and creatures from scratch while you keep the tempo you bought. The cleverness is that it sidesteps the usual ceiling on Storm payoffs, which mostly want to deal damage or generate mana: this one converts a long spell chain into pure tempo denial, and because it returns rather than destroys, indestructible and regeneration offer no protection. It does target, though, so anything with protection from blue, hexproof, or shroud simply cannot be picked up, and that target restriction is what stops a single resolution from being a clean board sweep. Where most Storm cards read as combo-piece-or-nothing (a single uninterruptible kill or a fizzle), this one reframes the mechanic as a one-shot tempo blowout: not a loop but a single enormous swing in board position, which has kept it appealing to decks that would rather strip an opponent's resources to nothing than burn them out in one explosive turn.
