So I am making an effect right now that requires you to make a gimmick. An unavoidable step during the making of this gimmick is the splitting of a card. Am I allowed to go over the general process for splitting a card in my tutorial, or would I have to redirect them elsewhere (ie. Blake Vogt's detailed instructions on the Marketplace). As a more general question, if someone has created a gimmick in the past that isn't necessarily generic level as of yet, and it were to be used in a completely new effect, would we be allowed to show it in the instructions (with their permission of course)?
