MTG Dimir Control Deck by Osgboy

Flash At the beginning of your upkeep, put an oil counter on this artifact. Instant and sorcery spells you cast cost {1} less to cast for each oil counter on this artifact.

Counter target spell unless its controller pays {2}. Corrupted — Counter that spell instead if its controller has three or more poison counters.

Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

Each opponent gets a poison counter. Draw a card.

Exile target creature if it has mana value 3 or less. Corrupted — Exile that creature instead if its controller has three or more poison counters.

As an additional cost to cast this spell, discard a card or pay 3 life. Destroy target creature or planeswalker.

Destroy target nonartifact creature.

Destroy target non-outlaw creature. (Assassins, Mercenaries, Pirates, Rogues, and Warlocks are outlaws. Everyone else is fair game.)

Return all attacking creatures to their owner's hand.

Search your library for an instant card or a card with flash, reveal it, put it into your hand, then shuffle. Flashback {5}{B} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Draw a card for each Island you control, then discard two cards.

Draw X cards. If X is 10 or more, instead shuffle your graveyard into your library, draw X cards, untap up to five lands, and you have no maximum hand size for the rest of the game. Exile Finale of Revelation.
