if i gain 2 same cards of the general skill dek, they triggers 2 times ex:

if i gain 2 points for any freebooter and choose the same card that gain 2 points for any freebooter, i gain 4 points for any freebooters?

my party chhose to stop this trik and we cant have 2 same cards but just one for tipe.

2 apotecary it's impossible also in the old board game, or 2 wizzard.

Yeah, I house rule that as a redraw too.

My gaming group usually uses the rule that an instance/requirement can't be used as a trigger/target for more than one card.

I don't know if this is what the developers intended, but considering the chance that the only time you would get stuck with two of the same upgrade is if you only get one draw/ one keep (meaning you have to keep the upgrade), it's possible you're at a loss.
