Steelclad Spirit⁣ - Innistrad: Crimson Vow⁣ (Common)⁣ [80]

Steelclad Spirit is a 3/3 creature with defender, meaning it can't attack unless something allows it to. However, whenever you play an enchantment, Steelclad Spirit gains the ability to attack that turn, effectively bypassing its defender restriction. This card is particularly useful in enchantment-heavy decks where you can consistently trigger its attack ability, turning a normally defensive creature into an offensive threat. The downside is that it requires you to have enchantments on the battlefield to make it useful for attacking, so if your strategy lacks enchantments, it may just sit there as a blocker.
