Some people get frustrated when they only have 1 shot at throwing a card and missing it like:
Ohhh ohhh Galey finally!!! Throws 2nd sliver card 97% fail.
So my suggestion is this let players be able to throw multiple cards to capture the arkadions they really want/need.
I agree but (at least in the case of the gold cards) the cost should not increase after a blocked capture. It’s bad enough on when I forget and end up having to spend 200 gold but 300
