Catharsis

Catharsis's first and second abilities care about what mana was spent to pay its total cost, not just what mana was spent to pay the hybrid mana symbols in its cost.

If this spell is copied, the copy will not have had any colors of mana paid for it, no matter what colors were spent on the original spell.

Catharsis's first and second abilities check to see if at least two mana of the appropriate colors were spent to pay Catharsis's cost. It doesn't matter if more than two mana of that color was spent; the effect isn't multiplied.
