Ok, I took the sub in our tight situation and won regardless of my bad play.
Can't build a 3rd graboid deck now, but don't have to build 5 decks with 151 cards.
Its a stupid rule withforcing salvage but we have to play it, lets hope this course of action was the best.
I decided to sub rather than cause a deliberate fault, this is because I'm honorable and tactical over cunning and exploitive, even tho the deliberate fault could have given us a better choice. I really think they need to fix the rules to keep us out of this situation. In almost any sport/competition it is allowed to take a voluntary penalty to avoid a disadvntage, but not being able to here sucks ruleswise.
PS - Good work team. Unlike our opponents we've never been forced to sub by our inactivity.
