Primal Prayers [Modern Horizons 3 Prerelease Promos]

When Primal Prayers enters the battlefield, you get EE (two energy counters).

You may cast creature spells with mana value 3 or less by paying E rather than paying their mana costs. If you cast a spell this way, you may cast it as though it had flash. When Gaea speaks, all of nature falls silent.
