Probably the latter.
I do wonder how the green Stompy version is going to deal with creatures AND the combo match-up more effectively. Chalice and Ballista are a nice start, but looking at Thalia Stompy, they seem to have so much more redundancy, even though they might lack a bit of consistency otherwise. Just look at the list at the
bottom:
- Combo disruption: Thalia, TKS, Chalice
- creature control: Displacer (+ Containment Priest), Ballista, Jitte, (Karakas)
I love the Snake, but green does rather poorly in terms of combo disruption and creature control. Until those issues are addressed, I don't think it's going to be better than Thalia Stompy, as the advantages seem rather small compared to it.
