Magecraft — Whenever you cast or copy an instant or sorcery spell, draw a card.

Flying When this creature enters, draw two cards. Evoke {2}{U} (You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters.)

Evolve (Whenever a creature you control enters, if that creature has greater power or toughness than this creature, put a +1/+1 counter on this creature.) Whenever an opponent casts a noncreature spell with mana value less than this creature's power, draw a card.

Look at the top three cards of your library, then put them back in any order. You may shuffle. Draw a card.

Choose one — • Target nonsnow permanent becomes snow until end of turn. • Target snow permanent isn't snow until end of turn. Draw a card at the beginning of the next turn's upkeep.

Switch target creature's power and toughness until end of turn. Draw a card.

Equipped creature has haste and shroud. (It can't be the target of spells or abilities.) Equip {0}

Avoidance — Whenever you cast a noncreature spell, exile up to one target nonland permanent you control, then return that card to the battlefield under its owner's control.

Exile two target artifacts, creatures, and/or lands you control, then return those cards to the battlefield under your control.

Put a flood counter on target land. That land is an Island in addition to its other types for as long as it has a flood counter on it. If you control a Merfolk, draw a card.

{T}: Add one mana of any color in your commander's color identity.

As this artifact enters, choose a color. Creatures you control of the chosen color get +1/+1. Whenever a land's ability causes you to add one or more mana of the chosen color, add one additional mana of that color.

Eluge's power and toughness are each equal to the number of Islands you control. Whenever Eluge enters or attacks, put a flood counter on target land. It's an Island in addition to its other types for as long as it has a flood counter on it. The first instant or sorcery spell you cast each turn costs {U} (or {1}) less to cast for each land you control with a flood counter on it.

{T}: Add three mana of any one color.

When this creature enters, untap up to seven lands.

Until end of turn, whenever a player taps an Island for mana, that player adds an additional {U}.

{T}: Add {C}. {1}, {T}, Sacrifice this artifact: Draw a card.

Flying When this creature enters, untap up to seven lands. {2}{U}{U}: Return this creature to its owner's hand.

(Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays {3}.)

Create a token that's a copy of target creature you control, except the token has flying and it isn't legendary.

The "legend rule" doesn't apply to permanents you control. Each legendary creature you control gets +1/+1. Each nontoken creature you control gets +1/+1 for each other creature you control with the same name as that creature.

Ward {2} As this creature enters, choose a creature type. This creature is the chosen type in addition to its other types. If a triggered ability of another creature you control of the chosen type triggers, it triggers an additional time.

Counter target noncreature spell.

Exile target creature. Its controller manifests the top card of their library. (That player puts the top card of their library onto the battlefield face down as a 2/2 creature. If it's a creature card, it can be turned face up any time for its mana cost.)
