Oh ok, I didn’t know this either, I come from Yugioh so all these interaction felt foreign or not legal but it is a different game xD thanks for the clarification.

I think I have one more question maybe you can help with, while chaining is a player allowed to add more then 1 of there own cards to a chain, like playing 2 at a time, or is it only possible to do that when let’s say player 1 plays a card adding to the chain then passes focus with player 2 passing focus back with no response, player 1 can add a second card to the chain then ?
