I'd also prefer combo elves to stasis-elves (at least on paper), but this thread was about playing stasis along root maze. Those 2 cards are quite unique and though they are symmetrical mabye a dedicated deck would take profit of them. The first brew I found looks crap, but better minds could arrive to a decent deck, who knows.
About "combish" elves, ubG does not appeal attractive to me. Surely is more resilient and plays more broken cards, but you are probably lighten manabase and elves density. I can accept uG to play call/beck, ancestral and time walk, or bG to add discard and decays (great cards against oath, worst matchup probably). monogreen is probably faster, has more density and it's cheaper for sure, thus more appealing

About skullclamp, I started playing 4 of them, but now I don't play any and I also don't miss them. I never played wirewood hivemaster, so I had to clamp my beautiful elves, and it didn't start until I had one heritage and 2 nettles,otherwise my mana flew away too quickly. Well, gsz would help a lot so it's probably viable, but gsz and clamp are prone to be countered. It's a version really worth trying.
Instead I chose glimpses, and 7 big mana elves (priests+archdruids) plus some expensive threats (regal force, genesis wave, emrakul, staff of domination -and I would try others in the future). Really different approach, can't say if better or worse.
