So I won a Relic (two relics, actually) against T50 the other day.
Since that time, whenever I beat Dream Catcher, I'll see a Relic show up in the spins. This shouldn't happen, right? The spins are based on your opponents decks, and Dream Catcher shouldn't have any cards that become relics. I don't think Dream Catcher has won any tournaments
.
I haven't yet seen it happen on other FGs, but I've seen Relics on over 5 (could be more, it's easy to lose track) different wins against Dream Catcher, and it shows up often.
