When this creature enters, choose one — • Create a 1/1 white Bird creature token with flying. • Return another target nonland permanent to its owner's hand. • Draw a card.

When this creature enters, reveal the top card of your library. If it's a land card, put it onto the battlefield. Otherwise, put that card into your hand.

Flying, ward {2} Channel — {2}{G}, Discard this card: Return target card from your graveyard to your hand. Channel — {1}{U}, Discard this card: Return target creature to its owner's hand.

Exalted (Whenever a creature you control attacks alone, that creature gets +1/+1 until end of turn.) {T}: Add {G}, {W}, or {U}.

Bestow {1}{G} Enchanted creature gets +1/+1. Landfall — Whenever a land you control enters, you may pay {1}{G} if this permanent is attached to a creature you control. If you do, create a token that's a copy of that creature. If you didn't create a token this way, create a 1/1 green Insect creature token.

Sacrifice a land: Target creature you control gains shroud until end of turn. (It can't be the target of spells or abilities.)

When this creature enters, look at the top X cards of your library, where X is your devotion to blue. Put up to one of them on top of your library and the rest on the bottom of your library in a random order. If X is greater than or equal to the number of cards in your library, you win the game. (Each {U} in the mana costs of permanents you control counts toward your devotion to blue.)

Flash When this creature enters, counter up to one target activated or triggered ability. If an ability of an artifact, creature, or planeswalker is countered this way, that permanent loses all abilities for as long as this creature remains on the battlefield. (Mana abilities can't be targeted.)
