Beast Within + Slippery Bogle

Overview
Slippery Bogle’s oracle text prevents your opponent from targeting it with Beast Within when they cast it, so Beast Within can’t be cast targeting an opponent’s Slippery Bogle. If Beast Within is on the stack with a target but that target is illegal by the time Beast Within would resolve, the spell won’t resolve and no Beast token is created (Ruling [2021-03-19]). If the target is legal when Beast Within resolves, the spell’s destroy effect is applied and the controller of the affected permanent creates the 3/3 Beast token, which is put onto the battlefield under that player’s control .
Step 1
Check targeting at cast time: Slippery Bogle’s oracle text says it can’t be the target of spells or abilities your opponents control, so an opponent may not choose it as the target for Beast Within when casting that spell.
Step 2
If a spell somehow exists on the stack with a target and that target becomes illegal before resolution (for example, the creature gained hexproof from some other effect or the target was removed), the spell won’t resolve and no Beast token will be created (Ruling [2021-03-19]).
Step 3
If Beast Within resolves with a legal target, it applies its instructions: destroy the target permanent, then that permanent’s controller creates a 3/3 green Beast creature token; the token is put onto the battlefield under that player’s control .
Step 4
After resolution, state-based actions and other checks happen normally (for example, if the token or other permanents have to be removed due to state-based actions) .
Resolution
An opponent can’t target your Slippery Bogle with Beast Within because Slippery Bogle’s text prevents opponents from targeting it. If Beast Within somehow is on the stack and its target is illegal by resolution, Beast Within won’t resolve and no token is created (Ruling [2021-03-19]). If the target is legal when Beast Within resolves, the destroy effect is applied and the controller of the permanent creates the 3/3 green Beast creature token and that token enters the battlefield under that player’s control .
