Change the text of target spell or permanent by replacing all instances of one color word with another or one basic land type with another until end of turn. Draw a card.

Choose one — • Counter target spell. • You may choose new targets for target spell. • Copy target instant or sorcery spell. You may choose new targets for the copy.

Counter target spell. If that spell is countered this way, put it on top of its owner's library instead of into that player's graveyard.

Put target permanent an opponent controls on top of its owner's library. That opponent may put an artifact, creature, enchantment, or land card from their hand onto the battlefield.

Change the text of target permanent by replacing all instances of one color word with another or one basic land type with another. (For example, you may change "nonblack creature" to "nongreen creature" or "forestwalk" to "islandwalk." This effect lasts indefinitely.)

Search your library for an instant or sorcery card, reveal it, then shuffle and put that card on top.

Choose one — • Target creature gains islandwalk until end of turn. (It can't be blocked as long as defending player controls an Island.) • Target creature gets +2/-1 until end of turn. • Target player discards a card.

Choose a card name, then target player mills a card. If a card with the chosen name was milled this way, you draw two cards. Otherwise, you draw a card.

Untap target creature an opponent controls and gain control of it until end of turn. That creature gains haste until end of turn. When you lose control of the creature, tap it.

Return target creature to its owner's hand. You create a token that's a copy of that creature.

Return target spell or creature to its owner's hand.
