MTG Mono Blue Midrange Deck by i_b_TRUE

Instant and sorcery spells you cast cost {1} less to cast. Whenever a spell or ability you control counters a spell, you may draw a card. If you do, discard a card.

When this creature enters, mill three cards. You may put a noncreature, nonland card from among the cards milled this way into your hand. If you don't, put a +1/+1 counter on this creature. (To mill a card, put the top card of your library into your graveyard.)

Offspring {4} (You may pay an additional {4} as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.) When this creature enters, look at the top four cards of your library. You may reveal a noncreature, nonland card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.

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.)

Blue spells you cast cost {1} less to cast.

Look at the top five cards of your library. Put two of them into your hand and the rest on the bottom of your library in any order.
