Well that's illegal so this card does nothing, unless it for whatever reason means the physical order of the side deck in which case it does even less than nothing.

It should be able to work. Iirc if a card contradicts a rule/mechanic, the card wins. In theory, this should be possible.

That implies you can use a Side Deck + are playing a match.

In singles, this is essentially useless for obvious reasons.

 

It can still work, but just that it'd be rather pointless.

"To add any five cards from your Side Deck to the top of your Deck. Then shuffle. " With the half life point cost for such a ridiculous thing, this would at least allow a player to recieve cards from their side deck during the duel to deal with certain aspects of the opponents deck they didnt expect. This is like how the side deck functions during a match(best of three) Except allowing you to tap into the usefulness ofyour side deck early to attempt salvaging a round during the round as opposed to losing it outright. A neat interaction that is ultimately a huge cost which could most likely backfire in the hands of inexperienced players. What I understand that a side deck for is for coverage. Usually the main deck will be kept to as close to 40 as reasonable for the strategy (typically exactly 40 for better chance of drawing potent cards) and your side deck is coverage. With the card as it is: The round is probably still lost if you really need to lose it and the half lp cost is then negligible. Toss in the fact that practitioners of this card are just making up for a failure to include proper meta/popular deck coverage in their side deck, a mistake in planning ahead of time.

 

Do with it as you will, but my suggestion keeps the lp cost relevant and also adds in the cost of deluding draw power or saving you from deck out.
