Playground with a full bench

[tinox6]

Am I allowed to use Playground with a full bench just to try and go to sleep? Thank you!

If you can fulfill the requirements for the attack, you can attack, even if it has no effect on game state, per this ruling:

This is different than playing a trainer to no effect, which is not allowed.

So, yes, you can Playground with both benches full.
