When Super Saiyan 3 Goku enters the battlefield, you may add 1 Ki counter to each other creature you control with a Ki counter on it.
At the beginning of your upkeep, you may tap 5 other saiyan creatures you control and sacrifice Super Saiyan 3 Goku. If you do, search your sideboard for a card named Super Saiyan God Goku and put it onto the battlefield.
