MTG 4/5c Omnath Deck by maicmaic

When Phlage enters, sacrifice it unless it escaped. Whenever Phlage enters or attacks, it deals 3 damage to any target and you gain 3 life. Escape—{R}{R}{W}{W}, Exile five other cards from your graveyard. (You may cast this card from your graveyard for its escape cost.)

When Omnath enters, draw a card. Landfall — Whenever a land you control enters, you gain 4 life if this is the first time this ability has resolved this turn. If it's the second time, add {R}{G}{W}{U}. If it's the third time, Omnath deals 4 damage to each opponent and each planeswalker you don't control.

Flash Lifelink When this creature enters, exile up to one other target creature. That creature's controller gains life equal to its power. Evoke—Exile a white card from your hand.

Flash Domain — This spell costs {1} less to cast for each basic land type among lands you control. When this enchantment enters, exile target nonland permanent an opponent controls until this enchantment leaves the battlefield.

Replicate {1} (When you cast this spell, copy it for each time you paid its replicate cost. You may choose new targets for the copies.) Counter target triggered ability or colorless spell.

Choose target creature or planeswalker. You get {E}{E}{E} (three energy counters), then you may pay any amount of {E}. Galvanic Discharge deals that much damage to that permanent.

Draw four cards, then put two cards from your hand on top of your library in any order.

If it's not your turn, you may exile a blue card from your hand rather than pay this spell's mana cost. Counter target noncreature spell. If that spell is countered this way, exile it instead of putting it into its owner's graveyard.

Converge — Exile target nonland permanent if its mana value is less than or equal to the number of colors of mana spent to cast this spell.

You get X {E} (energy counters), then you may pay any amount of {E}. Destroy each artifact, creature, and enchantment with mana value less than or equal to the amount of {E} paid this way.

Look at the top three cards of your library. Put one of them into your hand, put one of them on the bottom of your library, and exile one of them. You may play the exiled card this turn.

+1: Return up to one target land card from your graveyard to your hand. −1: Wrenn and Six deals 1 damage to any target. −7: You get an emblem with "Instant and sorcery cards in your graveyard have retrace." (You may cast instant and sorcery cards from your graveyard by discarding a land card in addition to paying their other costs.)

Each opponent can cast spells only any time they could cast a sorcery. +1: Until your next turn, you may cast sorcery spells as though they had flash. −3: Return up to one target artifact, creature, or enchantment to its owner's hand. Draw a card.
