If an effect would cause a player to shuffle one or more specific objects into a library, and a replacement or prevention effect causes all such objects to be moved to another zone instead, that library isn't shuffled.
Quote from nerdyjoe »So, I came up with a variation of the previous Conjurer's Ban puzzle. Here's the set up:
Your opponent went infinite, capsized your board, time twistered, tormod's crypted your graveyard, played elish norn, pacifism on elish norn, cast Sphere of Safety, cast Uba Mask, cast Nevermore naming Dark Ritual, cast Liquimetal Coating, made Nevermore an artifact, cast Karn, Silver Golem, made nevermore a creature, cast Soulfire Grand Master, cast Mirror Gallery, cast Mangara of Corondor, cast rite of replication kicked targeting Mangara and bought back with Soulfire Grand Master. Then they copy Nevermore for every non-land card in the game, ending with rite of replication. Then they use Mangara to exile liquimetal coating, Karn and Soulfire Grand Master. They then pass turn, and dare you to kill them. For simplicity, assume they have 15,000 Nevermores. How quickly can you kill them? They're at 20 life, 0 poison counters, 49 cards in their deck, 7 cards in hand. You have 7 cards in hand, you can stack your deck, and have up to 4 copies of non-basic cards.
Simple version: There's an Uba Mask, a Sphere of Safety, a Pacified Elesh Norn, and a Nevermore naming every non-land card on your opponent's side, you have no cards in play, and you can stack your deck. How fast can you win? [links added for convenience]
Proof that you can win: If your deck is 30,000 Forests, your hand contains 6 forests and a Treetop Village, you can play the Treetop Village, play all the forests, then activate treetop each turn, pay for the sphere, and swing 20 turns in a row. 30,024 turns.
