Rannot the Mystic

Instant and sorcery cards in your hand gain overload. Their overload cost is equal to the card's converted mana cost plus {5} (You may cast this spell for its overload cost. If you do, change its text by replacing all instances of 'target' with 'each'.)
"Over my years, I have learned to master the technique that many have tried to learn. The ability to be in mulitple places at once." -Rannot
