Lina, Izzet Polycaster

Each blue instant and sorcery spell you cast has replicate {u}{r} (When you cast it, copy it for each time you paid its replicate cost. You may choose new targets for the copies.)
Each red instant and sorcery spell you cast has overload X{u}{r}{r}, where X is that spell's mana cost. (You may cast it for its overload cost. If you do, change its text by replacing all instances of "target" with "each.")
