Here's my most current list of Winter Maze. It's got some nice synergies such as a soft lock with Winter Orb and Root Maze and you can crank out an insane amount of mana fast with Wild Growth + Utopia Sprawl + Arbor Elf. It's good match ups are Delver variants and D&T but it's bad match ups are Combo and Stompy lists. Not fully recommending this deck but it has some juicy synergies that some of you might be able to borrow in helping make Green Stompy a thing. Here's the list:

4x Arbor Elf
1x Carnage Tyrant
1x Dragonlord Atarka
4x Elvish Spirit Guide
1x Hornet Queen
2x Masticore
1x Progenitus

1x Scavenging Ooze
1x Thrashing Brontodon

EDIT: And btw, R3ndr0c I've been goldfishing your list and it feels strong! Sometimes I feel like I need more low cc threats to search out with GSZ but some of the opening hands are brutal! Natural Order is a bomb.
