You may pay 1 life and exile a blue card from your hand rather than pay this spell's mana cost. Counter target spell.

Flying Whenever an opponent draws a card, you may draw two cards.

Delve (Each card you exile from your graveyard while casting this spell pays for {1}.) Look at the top seven cards of your library. Put two of them into your hand and the rest on the bottom of your library in any order.

Reveal the top five cards of your library. An opponent separates those cards into two piles. Put one pile into your hand and the other into your graveyard.

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.)

Cumulative upkeep {1} (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.) Whenever an opponent casts a noncreature spell, you may draw a card unless that player pays {4}.

You draw two cards and you lose 2 life.

Flash If an opponent would draw a card except the first one they draw in each of their draw steps, instead that player skips that draw and you draw a card.

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.)

Delve (Each card you exile from your graveyard while casting this spell pays for {1}.) Draw three cards.

Council's dilemma — Starting with you, each player votes for time or money. For each time vote, take an extra turn after this one. For each money vote, choose a permanent owned by the voter and gain control of it. Exile Expropriate.
