Let's say I have deck without sleeves, and some cards in my deck are heads down(not upside-down, you don't see the images, but can recognize that some card backs are head down, while others not).
Can my opponent force me to look through my whole deck to fix that?
It happened in my club at least twice. I did not cheat, neither of us who were forced to do that make heads down cards on purpose(we shuffle like that, he insists that those cards may be lands or winconditions), but it eats lots of time to sort them back and is just annoying.
Can I at least force a player that don't like heads down cards(or judge?) to fix that instead of me, if it is in the rules?
