I already got Oshitsune so I only need Kolos, now.
I have 6 Harvey , 6 Hilly Billy, 5 Dr Falkenstein , 3 Saki , 3 Shifou , 2 Fanny , 2 Beeboy , 2 Kenny Cr , Clover and other cards of negligible value.
I know that the prices are kind of awkward to deal with but I'm just a beginner when it comes to trading.
P.S. Thank you ZacharyThomas and Artemis-BZ for the tips.
