Tutor

Search-your-library effects that fetch a specific card, either unrestricted or filtered by type, putting it into hand or on top of the deck. Demonic Tutor grabs any card to hand; Vampiric Tutor stacks the top of the library; Worldly Tutor finds a creature; Enlightened Tutor finds an artifact or enchantment; Mystical Tutor finds an instant or sorcery. Distinct from card_advantage.card_draw, which puts cards from the top of the library into hand without choosing which one, and from card_advantage.cantrip, which replaces a cheap spell with a blind draw. Basic-land searches belong with ramp rather than here, since they fix mana rather than fetch a chosen answer.
