Cobalt Golem⁣ - Mirrodin⁣ (Common)⁣ [157]

Cobalt Golem is a 2/3 artifact creature for four mana that can gain flying for a single blue mana, allowing it to evade ground blockers and attack over them. Its ability to fly can help in aggressive strategies or decks that focus on evasion and combat tricks. However, its relatively low power and toughness mean it can be easily removed if not protected.
