Unsanctioned Ancient Juggler

Indestructible is a static ability.

A permanent with indestructible can’t be destroyed. Such permanents aren’t destroyed by lethal damage, and they ignore the state-based action that checks for lethal damage (see rule 704.5g).

Multiple instances of indestructible on the same permanent are redundant.

“Bolster N” means “Choose a creature you control with the least toughness or tied for least toughness among creatures you control. Put N +1/+1 counters on that creature.”
