No other clan gets the kind of round win bonus for just 1 pill.
Montana at least have to spend two... When you can 1-pill in round 1 AND 2 and still have a 50/50 chance of winning, you know you are playing a broken clan.
But besides that,
Rescue is plagued with numerous problems. They have too many 6 powers, in a game where many strong cards have 8 or 7 and attack manip built in, or SoB. They have a lot of ability-reliant gap. And you can't half-deck to offset those weaknesses... In short I feel like
Rescue rely entirely too much on their bonus and win mostly by luck/stupid moves.
These are just my personal thoughts on the clan, nothing against you or your deck.
Also, I agree with Oracle --
Cliff is probably the most threatening card
Rescue has, because after all of their pill forcing, his Revenge will enable him to go through most DRs!
