Cards List
R 0165 – XLN
Whenever you cast a spell from your hand, reveal the top X cards of your library, where X is that spell's mana value. You may cast a spell with mana value X or less from among cards revealed this way without paying its mana cost. Put the rest on the bottom of your library in a random order.

- If a revealed card in your library has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
- For spells with {X} in their mana costs, use the value chosen for X to determine the spell's mana value.
- If the spell's mana value is 0, you do nothing as the ability of Sunbird's Invocation resolves.
