When you flip a coin, you are playing without a bid… but you technically get a russian bomber because that’s garg’s extra pain and death rule.
Usually when you accept a bidding system you agree to a negotiation and have to accept how that goes. Just because you bid down to 3 and your opponent says ok you have it… all of a sudden you don’t want it at 3… you now you want to flip for 0 or flip to give them allies @ 3? That is ridiculous.
You may as well just flip for sides.
Or you agree to a flip and just negotiate what the allies should get… then flip it for sides.
