Muzisitter's Appearance! not working as intended?

Skill:
The first 10 cards of both players Decks are sent to the Grave. 

If this happens, 10 random cards with a different name than this card are sent from your Grave to the bottom of your Deck. 

10 random cards are sent from the enemy Grave to the bottom of the enemy Deck. This card is removed from the game.

What I want to ask is, if I have less than 10 cards in deck with more than 10cards in grave this cards is supposed to work right? With the result of 10 cards in deck after use?

oh well, it's okay. i just hope we could have some kind of white tents

It's really annoying as hell when you got DC or RTO'd on the last floor of dungeon (vs boss) especially on muspelheim. Is there anything to do like Reconnecting? That socket nil value really make your effort become nothing. Thanks
