Opal Champion⁣ - Urza's Legacy⁣ (Common)⁣ [16]

Opal Champion is a two-mana enchantment from Urza's Legacy that transforms into a 3/3 Knight creature with first strike whenever an opponent casts a creature spell. This ability allows you to create a surprising blocker or attacker, punishing opponents for their creature-heavy strategies. It fits well in control or enchantment-oriented decks, but be mindful that it only activates under specific conditions. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
