// vs U.dec often side out Infernal Tutor because games slow down and to have access to it for Wish -> IT -> AdN

U Tempo (BUG / RUG / New Horizons): +1 Silence -1 Infernal Tutor
// No Xantid to avoid tempo loss to a removal spell

UW Control (Miracle / Blade): +2-3 Abrupt Decay +1 Silence -1 Empty the Warrens -1 Infernal Tutor -1 Chrome Mox (-1 Ponder)
// 3 Decays if Counterbalance. Side out if no permanent hate. EtW not desirable vs sweepers (Terminus, EE).

Merfolk: +2 Xantid Swarm +1 Silence -1 Infernal Tutor -1 Ponder -1 Duress
// Xantid because no removal, Ponder over Mox because need initial mana sources

Permanent-based hate (Maverick / Junk / Nic Fit / Elfball / MUD): +1 Cabal Therapy +2 Chain of Vapor +3 Abrupt Decay -3 Silence -2 Duress -1 Empty the Warrens
// EtW too slow, CoV/Decay to answer permanents, Therapy to help answer pre-emptively

Aggro (Zoo / Goblins): +1 Cabal Therapy +2 Chain of Vapor -3 Silence
// Minimal package to answer permanents (Thorn etc.)

Storm: +1 Cabal Therapy +1 Silence -1 Empty the Warrens -1 Ponder

Show & Tell (Sneak Show...): +2 Xantid Swarm +2 Chain of Vapor -2 Duress -1 Empty the Warrens -1 Ponder
// Xantid because no removal, CoV to answer potential white Leyline post-AdN. Silence out because need to stay fast, Xantid replaces it & easier to cast, and Duress takes their combo pieces.

Reanimator: +2 Xantid Swarm -1 Empty the Warrens -1 Ponder
