I am trying to design an interupt card mechanic in my CCG. (like Instant cards in MTG)
I am trying to decide whether to keep them on the player's hand (like MTG) or put them face down in play (like trap cards in Yugioh)
Which one is actually better? What are the pros and cons for them?
I would also like opinions on whether to include the "on the stack" mechanic (like chain effect in Yugioh) or make them be a effect resolve once the card come into play.
Please advice. Thanks
