“4, T: Roll a d20. Each opponent exiles cards from the top of their library until they exile an instant or sorcery card, then shuffles the rest into their library. You may cast up to X instant and/or sorcery spells from among cards exiled this way without paying their mana costs. <br><strong>1-9</strong> | X is one. <br><strong>10-19</strong> | X is two. <br><strong>20</strong> | X is three.”
