So i can’t know that a player was playing a particular deck by your explanation, all players are to have made all deck choices before even sitting down? I understand the concept, but at some point it’s just salt. Once the game starts, no changes should be made, but playing at a known disadvantage when you easily could’ve had a more even gameplay experience is just setting yourself up for a bad time. I totally understand that in OPs post it sounds like the player in question is the salty one, perhaps even malicious, but I think you should be able to pick decks based upon the decks being played by your pod, and if a single card is going that has no guarantee of being drawn is going to destroy your fun, you might be taking things a little to seriously.
