Sunbird's Invocation⁣ - Commander: Bloomburrow⁣ (Rare)⁣ [116]

Sunbird's Invocation is a five-mana red enchantment from the Bloomburrow Commander set that allows you to reveal the top X cards of your library whenever you cast a spell, where X is the spell's mana value. This ability lets you cast another spell for free, providing great value in spell-heavy decks, especially those focused on big, impactful spells. However, its effectiveness can be limited by the need for a diverse mana curve to maximise the number of spells you can cast for free.
