The Orcust lock “you cannot special summon, except dark monsters for the rest of the turn. Prevents you from activating chaos magic hats. Also i have tried using chaos magical hats without activating a orcust in the turn, which it allows me to do fine, but if i chain an orcust as chain link 3 the chaos magical hats revolves with out effect. So the orcust lock is stopping it. Checked with several judges, Chaos magical hats should resolve. Replicated the scenario several times, nothing else is preventing this
This is functioning correctly, per this similar ruling
But thats a case of a monster being treated as tuner, chaos magical hats summons the spell/traps as dark monsters
