I just want to say the card "Toy Emperor" is bugged. When it destroys a monster by battle it adds a trap card from your deck to hand. But after doing it you can't set it in that turn, infact you can't set any other card from your hand. And i think you can't activate any other card in that turn. Please investigate this issue.

it works fine on my end are you sure there wasnt a card in play that prevented you from setting cards

I was using it on ygopro and not on mackpro if that helps.

I don't remember using any effect like that, never worked for me.

oh i dont use ygopro so cant help you there but i know the mackpro version works fine

Ok, i will test it in mackpro, in ygopro it should work just as fine.

well mackpro does use different scripts then ygopro so there could be a prob with ygopros script
