Quote from DrawmeomgFair enough.
Let me clarify my position. I've been waxing overly wordy and it's getting in the way.
1. Allies are in my opinion at minimum a solid deck. I am certainly not arguing they're BAD, or even not quite good.
2. I haven't seen the kinds of competitive results that make me think allies are top tier (I just fact-checked myself at starcitygames looking at the GP:KL and the PT:SD results).
3. I don't think drawing conclusions from MTGO daily events is a particularly safe thing to do (I mean I know the decks I've taken into them and done well with - and I'm a pretty bad player in general), unless you've got an enormous sample size suggesting that the deck is doing phenomenally. Seeing 4 Jund in every top 8 of course suggests Jund is amazing. Seeing a deck here and there demonstrates that the deck is at least solid, but I don't think you can take anything more away from it than that.
I don't mean to put the deck down. I just think it's premature to step up and say that allies are "ripping up" MTGO because of a handful of decent placements in daily events.
Everyone, for the revised version of the OP, replace "ripping up" with "doing moderately well on"
