Plasma Behemot & Dagger of Unmaking

[Keith☆Star]

So I faced this so called "bug" when playing yesterday

I used DMT's ability and played Plasma Behemot and passed the turn
My opponent played Dagger of Unmaking and attacked my PB, which returned to my hand
He then passed me the turn
I played again PB after using DMT's ability and then passed the turn
He played Bad Santa, Jasmine and Birgitte then attacked my PB again, but this time it didnt return to my hand inflitting him 3 dmg

Did you have 4 or higher number of cards in hand when he played Bad Santa?

If Bad Santa filled up your hand to seven cards, PB would not be returned by DoU because you can never have more than 7 cards in your hand by any means. Actually good for you that your opponent either didn't know or consider this in this game, he should've bounced PB first, then used Bad Santa, that would've allowed him to put PB back in your hand and get fewer cards from Bad Santa draw.

I'm going to watch the match and then reply back here, as everyone has said its likely that your hand became full and thus the PB couldn't be bounced back. Welcome back btw KeithStar.

EDIT: Yep your hand was filled to 7 (the max) when he played Bad Santa, thus the PB couldn't be returned to your hand because you were at the hand size limit.
