Whoever (Xouman!) said to play BUG is right on the money. That deck is easy to pilot so being away from the format for a while won't be a huge problem. Deathrite is great against this field. Trygon predator is also a nearly instant-win against this field. Also you'll love Abrupt Decay (best anti-oath card since trygon). So some kinda bug fish list with trygon, deathrite, bob, tarmogoyf, wastelands, FoW, spell pierce, etc. Looks like a lot of graveyard based strategies, actually, so something like surgical extraction in the board might be strong.
The big key is its a very strong archetype that has no representation in the meta, so hopefully people will be unprepared.
Also 2 dredge decks out of 12 total seems like a LOT of dredge to me. So, yeah, bring your cages.
Not a bad call, as a BUG list just won BOM7.
