MTG WBRG Aggro Deck by Altheriax

Companion — Each permanent card in your starting deck has mana value 2 or less. (If this card is your chosen companion, you may put it into your hand from outside the game for {3} as a sorcery.) Lifelink Once during each of your turns, you may cast a permanent spell with mana value 2 or less from your graveyard.

A-Cauldron Familiar can't block. When Cauldron Familiar enters, each opponent loses 1 life and you gain 1 life. Sacrifice a Food: Return Cauldron Familiar from your graveyard to the battlefield.

When this creature dies, seek a creature card with mana value 3 or less. That card perpetually gains haste, "This spell costs {1} less to cast," and "At the beginning of your end step, sacrifice this creature."

When this creature dies, exile the top two cards of your library. Until your next end step, you may play one of those cards.

First strike When this creature enters, you get {E}{E} (two energy counters). Then if you cast it from your hand, exile cards from the top of your library until you exile a nonland card. You may cast that card by paying an amount of {E} equal to its mana value rather than paying its mana cost.

Sacrifice another creature or artifact: Put a +1/+1 counter on Bartolomé del Presidio.

Whenever another nontoken creature you control enters, create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this token: You gain 3 life.") Sacrifice three Foods: Return target historic card from your graveyard to your hand. (Artifacts, legendaries, and Sagas are historic.)

Sacrifice a creature: This enchantment deals 1 damage to any target.

At the beginning of your end step, if you control a creature, look at the top seven cards of your library. Then you may sacrifice a creature. If you do, you may put a creature card with mana value X or less from among those cards onto the battlefield, where X is 1 plus the sacrificed creature's mana value. Put the rest on the bottom of your library in a random order.
