MTG Mono Red Aggro Deck by esmyth

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 this creature deals combat damage to a player, you may sacrifice it. If you do, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.) When this creature dies, it deals damage equal to its power to any target.

Valiant — Whenever this creature becomes the target of a spell or ability you control for the first time each turn, put a +1/+1 counter on it. When this creature dies, it deals damage equal to its power to each opponent.

Haste Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)

Prowess If a source you control would deal noncombat damage to a creature an opponent controls, put that many -1/-1 counters on that creature instead.

Trample, haste Whenever this creature deals combat damage to a player, return a land you control to its owner's hand.

Target attacking creature gets +3/+3 until end of turn. If it's an artifact creature, it gains trample until end of turn.

Target creature gets +2/+0 until end of turn. Create a Monster Role token attached to it. (If you control another Role on it, put that one into the graveyard. Enchanted creature gets +1/+1 and has trample.)

Target creature gets +3/+1 until end of turn. Scry 1. (Look at the top card of your library. You may put that card on the bottom.)

Target creature gets +3/+0 until end of turn. When it dies this turn, manifest dread. (Look at the top two cards of your library. Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.)

As an additional cost to cast this spell, sacrifice a creature. Thud deals damage equal to the sacrificed creature's power to any target.
