MTG Boros Midrange Deck by kasiso

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 another creature you control enters, you gain 1 life and get {E} (an energy counter). Whenever you attack, you may pay {E}{E}{E}. When you do, put two +1/+1 counters and a flying counter on target attacking creature. It becomes an Angel in addition to its other types.

First strike, lifelink Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.) At the beginning of your end step, if you gained life this turn, create a 1/1 white Cat creature token. Then if you have the city's blessing, for each token you control that entered this turn, create a token that's a copy of it.

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.)

Whenever Haliya or another creature or artifact you control enters, you gain 1 life. At the beginning of your end step, draw a card if you've gained 3 or more life this turn. Warp {W} (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)

When this creature enters, discard two cards, then draw two cards. For each nonland card discarded this way, create a 1/1 red Elemental creature token. {3}{R}{R}, Exile this card from your graveyard: Create two 1/1 red Elemental creature tokens.

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 When this creature enters, search your library for a basic Plains card or a creature card with mana value 1 or less, reveal it, put it into your hand, then shuffle. Warp {1}{W} (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)

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.

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.

This land enters tapped unless you control a Mountain. {T}: Add {R}. {R}, {T}, Exert this land: Add {R}{R}. If that mana is spent on a creature spell, it gains haste until end of turn. (An exerted permanent won't untap during your next untap step.)
