MTG Mono Blue Control Deck by HamHocksMTG

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.)

{2}, {T}: Draw a card, then discard a card. Create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

Surveil 3. (Look at the top three cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) Flashback {1}{U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Counter target noncreature spell unless its controller pays {2}.

Spree (Choose one or more additional costs.) + {1}{U} — Counter target spell. + {3} — Create a token that's a copy of target artifact or creature you control. + {2} — Draw two cards, then discard a card.

Counter target noncreature spell.

Exile target nonland card in a graveyard that was put there from anywhere this turn. Copy it. You may cast the copy without paying its mana cost.

Draw cards equal to the number of cards in your library, then put a card from your hand on top of your library. You have no maximum hand size until your next turn.

If you would draw a card while your library has no cards in it, you win the game instead. +1: Target player mills two cards. Draw a card. −8: Draw seven cards. Then if your library has no cards in it, you win the game.

+1: Draw a card. Target player mills a card. 0: Target player mills ten cards. −7: Any number of target players each draw twenty cards.

This land enters tapped unless you control an Island. {T}: Add {U}. {2}{U}{U}, {T}: Scry 2.

({T}: Add {U}.)
