A bug and insect centric archetype for green, would definitely be a green red archetype but so far is favoring being just mono green because of themes

Megabugs is a go-wide archetype where a lot of it's balloons either go to the breath zone after they've been popped, and has mechanics to ramp by specifically searching and putting megabugs in the breath zone and then using card effects to send them out in one Mass swarm.

This deck wants to try and win through raw numbers, however rather than spamming small balloons, it wants to get the resources to continuously throw down mid-sized balloons and send them out the breath zone as well.
