Choose two or four — • Return target creature to its owner's hand. • Return target spell to its owner's hand. • Return target sorcery card from your graveyard to your hand. • Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)
Archive 5 (As this enters, shuffle the top five cards of your main library into a new face up library. Sacrifice this after the archived library is empty.) If you would draw a card from an archived library, draw a card from each of your archived libraries instead. (Archived libraries are those that still have their Study in play.)
(Activate each submodule once as a sorcery. When this enters, activate one submodule for free.) {U}{U}{U}: Premise Create a token that's a copy of target creature. {U}{U}{U}: Inference Tap all creatures target player controls. Those creatures don't untap during that player's next untap step. {U}{U}{U}: Conclusion Logic Module gains “Whenever a creature you control deals combat damage to an opponent, you may draw a card.”
Take an extra turn after this one. Exile Look to the Future. Civilized — If you control an artifact, a creature, and an enchantment, until the end of your next turn, you may look at the top card of your library any time and you may play the top card of your library.
Return target nonland permanent to its owner's hand. Dominance — If you control the creature with the greatest power or tied for the greatest power, you may put that permanent on top of its owner's library instead.
Counter target spell, activated ability, or triggered ability. Its controller chooses draw step, main phase, or combat phase. That player skips each instance of the chosen step or phase during their next turn. (Mana abilities can't be targeted.)
Put target nonland permanent on top of its owner's library. Create a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”
Look at the top three cards of your library. Put one of them into your hand. Put Lost in Deep Storage and the rest on the bottom of your library in any order.
Nearly everything that Entela has ever written is in Deep Storage somewhere. The trick is in tracking it down.
Enchant creature When Lost to the Elements enters, if enchanted creature isn't in a pack, tap it. (Two or more creatures with the same controller and equal power are in a pack.) Enchanted creature doesn't untap during its controller's untap step.
Draw a card. Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)
Faith in a conjecture meets the challenge of proving it.
Whenever you cycle a card, scry 1. (Do this before you draw.) {W}{U}{B}{R}{G}, Sacrifice Maelstromancy: Return up to three target cards with cycling abilities from your graveyard to your hand.
Choose two — • Target player creates a 1/1 blue Wizard creature token with prowess. • Target player draws two cards, then discards two cards. • Tap up to two target creatures. • Target creature or player gains hexproof until end of turn.
