Vanishing 3 (This permanent enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.) Whenever a time counter is removed from Thespian's Finale, create a token that's a copy of target creature. Sacrifice that token at the beginning of your next upkeep.
When Theurgist of the Depths enters, for each card type, you may exile a card of that type from your graveyard. Target opponent separates those cards into two piles. Put all cards from the pile of your choice into your hand. Recite {B}{G}{U}(You may cast this creature from your graveyard for its recite cost. If you do, exile it when it enters or if it would leave the battlefield.)
Whenever Thicketkeeper perseveres, add {G}{G}. Until end of turn, you don't lose this mana as steps and phases end. (A creature perseveres when it survives damage.)
Flying When Thief of Mortals deals combat damage to a player, as long as you control Thief of Mortals, gain control of target nonland permanent that player controls, and that permanent doesn't untap during its controller's untap step. Tap it. At the beginning of each end step, if you control five or more permanents you don't own, you win the game.
Choose two — • Scry 3, then you may mill up to three cards. • Each opponent loses 3 life. • You draw a card and you lose 1 life. • Return a creature card from your graveyard to your hand.
Search your library for a nonland card not named Thin the Veil, exile it, then shuffle. If it has mana value less than or equal to the number of card types among cards in your graveyard, you may cast it without paying its mana cost. If you don't, put it into your hand.
When Third Legion Rider enters, if you control an embattled creature, tap target creature an opponent controls. It doesn't untap during its controller's next untap step. (A creature is embattled if it has a counter on it or has a permanent you control attached to it.)
Rhapsody {4}{U}{U}(Pay {4}{U}{U} to cast this as a 4/4, or as a sorcery to make it become a 4/4.) Whenever you draw a card, any number of target players mill two cards. Whenever This Is Not Our Fate deals combat damage to a player, for each player, you may cast an instant or sorcery card from that player's graveyard without paying its mana cost.
Primal {5}{R}{W}(During your turn, you may cast this spell for {5}{R}{W} instead of playing a land.) Until end of turn, permanents you control gain indestructible and permanents you don't control lose indestructible. Then if if this spell was cast for its primal cost, destroy all nonland permanents.
Target player mills five cards. Draw a card for each card type among cards milled this way. (The card types are artifact, creature, enchantment, land, instant, planeswalker, sorcery, and tribal.)
