Early game keeps good, hag/turb are strong on curve and prob bad after so a decent keep id imagine. Cruiser might be the nuts w/ another elemental. All the roid cards are eles which just makes it a 3 mana 4/5 rush, not bad on curve.
Main idea is to otk with a murmur gatekeeper turn, with generic good stuff cards to fill out the curve, john hearthstone is ceaseless expanse (couldn’t find in the deck builder).
Many many ways to build something similar to this but its difficult to pick a direction without knowing the meta you’re playing it into.
Notable ideas:
Spell damage (zapper or oracle) does work with the roids/eruptions. Would be good to run magma with this.
Really not sure if sasquawk/turbulus are any good, the parrot doesn’t repeat battlecries so its only really good with ceaseless/titan/spells.
Ceaseless could be a meme, but if it finds a home a deck like this seems the most likely.
The early game could change a lot depending on whats needed. Mauler might be bait. Early game overload cards to enable flowrider could be the play. Other removal like volcano or gift might be good.
Finally you probably find a way to run strong staples like zilly/gorgonzormu etc. but without knowing which ones or what to cut its just speculation.
