can j t use his efect to add a foundation he shares no simbols with to his staging area?

"After any player plays a foundation, their opponent may add a foundation they could normally play to their staging area committed from their hand."

when can you play a card you don't share resources with?

then normally play to your staging area would refer to wether it shares symbols. thanks, i was just making sure.

Note that the "you could normally play" part refers to the current state, so if you have any cards in your card pool you have to conform to the current resource chains, not just resources on your character.

This character is now officially banned from tournament play
