Ok, so I have three extra Gilgamesh cards, and two extra Saber cards; is it worth trading these five extra cards for a Rin card? I also Have both Saber and Saber Alter (not part of what I'm calling extra). Total I have pulled Saber and Gilgamesh each four times. I have every other character form the collab and I think it would be awesome if I had all possible cards from a single collab, but I don't want to if it's worth keeping the extra cards. Worse case I could drop some money on the special stone deal and get a guaranteed 6* from the collab and 20 stones.
