Goblin Fire Fiend⁣ - Ravnica: City of Guilds⁣ (Common)⁣ [127]

Goblin Fire Fiend has haste, allowing it to attack immediately, and it must be blocked if possible, which can force your opponent to commit resources to defence. For just one red mana, you can pump its power temporarily, making it a threat that can pressure your opponent and potentially trade up in combat. It fits well in aggressive red decks that seek to overwhelm opponents quickly.
