Hearthpwn

Meme decks are the best decks.

Don't be a degenerate and play the following decks:

Big Priest

Exodia/Aluneth/Quest Cyclone

Odd Paladin

Kingsbane Mill Rogue

Even Shaman

Naga Seawitch 

If you unironically ladder with these decks and play them in casual, I hope your family has a nice christmas.
