MTG Mono Red Midrange Deck by Yhwach

Haste (This creature can attack and {T} as soon as it comes under your control.) {T}, Sacrifice this creature: It deals 1 damage to any target.

Other Goblins you control get +1/+1. Whenever this creature or another Goblin you control dies, exile the top card of your library. If it's a Goblin creature card, you may cast that card until the end of your next turn.

Start your engines! Other Goblins you control have haste. At the beginning of combat on your turn, create a 1/1 red Goblin creature token. That token attacks this combat if able. Max speed — {T}: Add {R} for each Goblin you control.

Haste Whenever Squee attacks, create a 1/1 red Goblin creature token that's tapped and attacking. You may cast this card from your graveyard by paying {3}{R} and exiling four other cards from your graveyard rather than paying its mana cost.

{T}: Create X 1/1 red Goblin creature tokens, where X is the number of Goblins you control.

Whenever a creature you control enters, this enchantment deals 1 damage to each opponent.

Bargain (You may sacrifice an artifact, enchantment, or token as you cast this spell.) Torch the Tower deals 2 damage to target creature or planeswalker. If this spell was bargained, instead it deals 3 damage to that permanent and you scry 1. If a permanent dealt damage by Torch the Tower would die this turn, exile it instead.

This spell costs {1} less to cast for each creature that attacked this turn. Witchstalker Frenzy deals 5 damage to target creature.

Create two 1/1 red Goblin creature tokens.

({T}: Add {R}.)

Start your engines! (If you have no speed, it starts at 1. It increases once on each of your turns when an opponent loses life. Max speed is 4.) {T}: Add {C}. Max speed — {T}: Target creature gains haste until end of turn.
