This is a grindy midrange mirror-style matchup against another Thoughtseize/counterspell/Orcish Bowmasters deck, so White Orchid Phantom provides an efficient flying first-strike clock that also strips a nonbasic land, punishing their fetch-heavy, tapland-heavy manabase. Mystical Dispute is cheap and can counter their Counterspell, Force of Negation, or Preordain for as little as one mana unless they pay {3}, while still countering anything else unless they pay {3}. Witch Enchanter is trimmed since it lacks targets against a deck without artifacts or enchantments, and one Prismatic Ending is trimmed as well. Keep Thoughtseize, Solitude, and Fatal Push at full count since they remain premium disruption and removal in this matchup.
