Design a card with traditional (two-colored) hybrid mana in its mana cost, a card with snow mana (S) in its mana cost, and a card with 10 or more generic mana in its mana cost.
Quote from Subject16 »Refractive Blast
Converge— When you cast Refractive Blast, copy it X times, where X is the number of different colors of mana spent to cast it minus one. You may choose new targets for the copies.
Refractive Blast deals damage equal to the amount of R spent to cast it to any target.
