Golden Bonnie

When Golden Bonnie enters the battlefield, if it wasn't cast, create 5 Child Tokens.
At the beginning of your pre-combat main phase, sacrifice as many Child Tokens as possible.
When you do, create 5 Spirit Tokens. Each Spirit Token then deals damage equal to its
Toughness to Golden Bonnie.
When Golden Bonnie dies, exile it, search your hand, graveyard, or library for a card named "Springtrap."
Put that card onto the battlefield tapped. Springtrap is now treated as your commander.
