Pichu, Super-Charged Shock

Triple strike
When Pichu deals combat damage to a player,
you get {e}.
If a red or white source would deal damage, it
deals double that damage.
Pay X {e}: Pichu deals X damage to target
creature. If X is more than 9 after this phase,
there is an additional combat phase after this
phase. Untap Pichu and target red or white
creature at the beginning of that combat.
