I think it's safe to say that we'll start to see Dracotail entering the the meta-sphere in a more dominant way going forward. Particularly Branded Dracotail builds.
Yummy is still going to be extremely dominant especially post DOOD.
Mitsurugi and Fiendsmith being unhit but having the cards that bridge into them being removed means that these archetypes are still going to be powerhouses when they do show up.
Malice is probably dead for the most part competitively. Not saying you won't see any but they ain't winning any events, way too inconsistent now. That's including the lower number of Lancea's we'll see too btw, it doesn't make a difference.
VS is a lot weaker and I anticipate them dropping off significantly too, definitely not the best deck of this upcoming format. Far from it.
Last little prediction but the rogue decks we currently have + the ones we expect to see post DOOD will be that much better now since the power level of the game just took a fairly decent sized hit. Yes, JUHU still remains dominant, but I can see some other deck taking tournaments from the JUHU decks every now and then.
