I look forward to testing this. It looks awesome. Initial thoughts.

Seems like Relic trumps crypt here, especially because the rock is the main matchup where you are bringing in the crypt. Sure, it might hit a Hammer every now and again, but most of the time, it's going to shrink potential tarmogoyfs, cantrip, and blunt life from the loam way more effectively. It's also much better against the Martyr/Proc decks because they put so few cards into the yard.

Splash damage- Decks are already bringing in CoP and Forgetender's in against everything from burn to swans. CoP's aren't that bad with your stuffy doll, but forgetender's seem scary out of zoo. I don't really have an answer for them blanking your wraths except maybe to play more wraths.

Burn's sulfuric vortex plan is going to trump your sun droplets. Shunt's sweet, but I worry it's not enough.

Swans just seems terrible if they know what you're doing. They've got gigadrowse and you don't really have a clock. They aren't going to drop a swans against a deck with skred until you're tapped out. But meta's will differ, maybe you just don't hit it. Do you really bring in Droplets here?

Blood moon is great, but I've definitely read that decks are adapting to it. Like Artowis, I'm not sure that Tron falls in the top 6-7 decks. Maybe you just want molten rain?
