Dispersing Orb
Most blue tempo answers fire once and leave: a counterspell stops a single spell, a Boomerang buys one turn before it goes to the graveyard. This sits on the battlefield and turns any spare permanent into a hand-back, regardless of type: lands, creatures, artifacts, enchantments, planeswalkers, even itself if you need the exit. The activation is deliberately expensive on both axes, mana and the permanent you feed it, and that double cost is the brake. You cannot loop two bounces a turn off one untapped supply, and the sacrifice clause means every use surrenders a board piece. The intent reads as a grind engine for the long control mirror, where the thing you sacrifice is often a creature already on its way out, a token, or a tapped-out spare, and the thing you bounce is an opposing threat returned to its owner's hand, forcing them to recast it and spend the tempo all over again. It plays like a Man-o'-War's bounce effect handed to a permanent and metered by a tax: trade the one-shot tempo swing for an answer you can aim at anything, repeatedly, provided the fuel holds. The color-locked, type-agnostic flexibility is the draw; the resource drain is the reason it never becomes a hard lock.
