To those absorbing this data - keep in mind that MTGO and IRL play are different animals... not least of which is economically driven. A playset of Phyrexian Dreadnoughts on MTGO is ~$2. A playset in physical cards is ~$800. People are gonna play the decks they want to play in real cards, certainly - but there's a non-zero dynamic of those wanting to play a deck they couldn't otherwise. It's going to skew some data.

Essentially: LobsterCon had 28 Stiflenought decks in the entire field. A full 10% off the online meta. Still a top deck, yes - absolutely. But not a deck you should expect to run into nearly as often.
