This maybe is a weird and stupid question. My opp summons blowback. I activate bottomless and he uses his effect. He tosses his coin by catching it in the air and lay it on his hand(hope you understand). I don't agree with it and I say that he is not allowed to catch the coin. If he tosses his coin, he must let it fall on the table(That's what I say). What should we do? Call a judge...?
