a few hundred?? i get bored to death just going through 50 of them, and I have about 1100 of them now, but only had about 100 before gambit. Go figure where all my money went. Although, I don't think I lost as much as when I used elixirs.
Oh, and I have about 120 R and SR cards left to level up, so don't think I will run out any time soon.
