Goku the Returned

Exalted, First Strike, Flying, Haste
When Goku the Returned enters the Battlefield, he gains +3/+3 until the end of the turn. Opponent creatures must block him this turn if able.
Whenever a Z Fighter creature you control dies, you may pay X Life, where X is equal to that Z Fighter's converted mana cost. If you do, Transform Goku the Returned into Super Saiyan Goku.
