Overclocked Electromancer

Creature — Lizard Wizard

At the beginning of combat on your turn, you may pay EEE. If you do, put a +1/+1 counter on this creature. Whenever this creature attacks, double its power until end of turn. Whenever this creature deals combat damage to a creature, if that creature was dealt excess damage this turn, you get X E, where X is that excess damage.
