[confirmed]Commanders vs Rule of Law / Arcane Lab

[Nexhro]

Describe the Bug:
Rule of Law and Arcane Laboratory don't prevent a player from casting his/her commander from the command zone if he/she has already cast a spell that turn.

If the commander is the first spell cast on a given turn, Rule of Law / Arcane Laboratory correctly prevents that commander's controller from casting additional spells that turn.
