Overwrite the Multiverse

4-Color Control can use this as one- or two-copy top end: slower than Deadly Cover-Up, but a populated board leaves a real Jace resource.

Could be wrong if Control may value Deadly Cover-Up's five-mana timing and deck-exiling clause more than the Jace payoff.

Creature-light black control may test it, but Farewell is far broader at the same cost; the Jace payoff rarely offsets BB and sorcery speed.

Could be wrong if A successful black control shell with reliable double black could make the card a more regular top-end choice.

A six-mana BB creature-only sweeper is behind Terminus and cheaper interaction; its Jace upside needs a large board and no listed shell wants it.

Could be wrong if A viable black big-mana or control shell could make the exile-plus-Jace package more attractive.

All Is Dust serves big-mana decks more broadly; this demands BB and only hits creatures, so its six-mana payoff is unlikely to earn slots.

Could be wrong if A black-enabled Cloudpost configuration could cast it reliably enough to exploit its lower nominal cost.

An exile wipe often leaves a high-loyalty Jace in multiplayer. It is more immediate than Ondu Inversion, but misses artifacts and enchantments.

Could be wrong if Optimized lists may prefer cheaper sweepers, while low-creature tables can leave Jace with too little loyalty.

A six-mana exile-all-creatures reset often leaves enough loyalty to draw and surveil, making it a strong first pick rather than a self-contained win condition.

Could be wrong if Unknown speed, fixing, and removal density could make six mana or double black substantially more punishing.
