Cyclonic Riftremoval$29.83A classic blue reset spell that can sweep away an opponent's board at instant speed, with an overloaded mode that functions as a game-ending tempo swing. It is the closest upgrade-style analogue to a mass-bounce effect in blue.
BoomerangremovalBudget$0.32Simple blue bounce that can hit any permanent, preserving the tempo-oriented play pattern of Sunder. It is far narrower in scale, but serves as a low-cost functional alternative for land disruption or permanent reset.
EvacuationremovalBudget$0.77Instant-speed blue reset that bounces all creatures, giving a similar board-wipe tempo role. It does not affect lands, but it fills the same 'reset the game state at instant speed' niche in blue.
Devastation TideremovalBudget$0.46Mass bounce spell that can clear the battlefield and create a huge tempo advantage, much like Sunder. The miracle discount can make it dramatically cheaper, though it hits nonland permanents rather than lands.
Wash OutremovalBudget$0.40A blue mass-bounce spell that can effectively clear a color from the board and function as a sweeping tempo play. It is less universal than Sunder, but similar in using bounce as a reset tool.
AetherizeremovalBudget$0.34A blue instant that punishes attacking creatures by bouncing them all, offering a defensive version of the same tempo swing. It is narrower than Sunder, but comparable as an instant-speed reset effect.
AetherspoutsremovalBudget$0.62An instant-speed blue defensive reset that can place attacking creatures on top of their owners' libraries or into their libraries. It fills a similar role of turning combat into a massive tempo loss for opponents.
Mana Vortexutility$14.27A blue enchantment that steadily destroys lands and captures the same land-denial philosophy as Sunder. It is slower and more attrition-based, but very similar in strategic purpose.
