Considering that for a long time now most of the lists that get published to the decklist sites are from MTGO, where only decks that differ from the others by X cards are disclosed, and the impact of the dozen or two very skilled regular MTGO players, I think it would be best to stop pretending that the metagame percentage numbers given by the decklist sites really mean very much.

It would be better to just acknowledge the subjective nature of a list like this, choose one dedicated person who keeps up with the format, and have them just pick out the five or six decks or deck archetypes they think players should be focused on for testing and deck tuning if they have a sizable upcoming tournament with an unknown metagame.

If that person were me and I were to make such a list today, I would probably choose:
  • Blue-Red/Grixis Delver
  • Bant Snow Control
  • Jeskai Breach
  • BUG Zenith Oko
  • Death & Taxes/Maverick


Obviously I'm cheating a bit here by grouping some things together.
