I have immediately conceded against Duress, deep cavern bat, etc etc etc etc over 1000 times immediately as soon as the cards drop on turn 1 or 2. The match maker should notice this behavior and realize its just giving free wins away on turn 1/2 making matches take 5s to complete. This is a terrible play experience for everyone involved and more importantly, this ensures people playing targeted discard are in your app for less periods of time (which directly translates to less money in your pocket, which your shareholders should actually care about). Maybe an instant concesssion 20 times in a row should just stop matching players against that card with the deck they are trying to use
