MTG Mardu Midrange Deck by Doomenstein

Companion — Your starting deck contains only cards with odd mana values and land cards. (If this card is your chosen companion, you may put it into your hand from outside the game for {3} as a sorcery.) If a source you control with an odd mana value would deal damage to a permanent or player, it deals double that damage to that permanent or player instead.

Whenever Ragavan deals combat damage to a player, create a Treasure token and exile the top card of that player's library. Until end of turn, you may cast that card. Dash {1}{R} (You may cast this spell for its dash cost. If you do, it gains haste, and it's returned from the battlefield to its owner's hand at the beginning of the next end step.)

Flying When this creature enters, exile another target permanent. Return that card to the battlefield under its owner's control at the beginning of the next end step.

Menace, lifelink, indestructible Ketramose can't attack or block unless there are seven or more cards in exile. Whenever one or more cards are put into exile from graveyards and/or the battlefield during your turn, you draw a card and lose 1 life.

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.)

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.

Flying Plainscycling {2} ({2}, Discard this card: Search your library for a Plains card, reveal it, put it into your hand, then shuffle.) Eternalize {2}{W}{W} ({2}{W}{W}, Exile this card from your graveyard: Create a token that's a copy of it, except it's a 4/4 black Zombie Dragon with no mana cost. Eternalize only as a sorcery.)

Impending 5—{1}{B} (If you cast this spell for its impending cost, it enters with five time counters and isn't a creature until the last is removed. At the beginning of your end step, remove a time counter from it.) Whenever this permanent enters or attacks, mill four cards, then you may return a non-Avatar creature card or a planeswalker card from your graveyard to your hand.

{T}: Target player exiles a card from their graveyard. {1}, Exile this artifact: Exile all graveyards. Draw a card.

As an additional cost to cast this spell, you may exile any number of white cards from your hand. This spell costs {2} less to cast for each card exiled this way. Exile target artifact, creature, or enchantment with mana value X or less.

Destroy target creature if it has mana value 2 or less. Revolt — Destroy that creature if it has mana value 4 or less instead if a permanent left the battlefield under your control this turn.

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.
