Was one of the two OG blue classes before the shift towards the more Eastern ninja direction, while Lifesavers are getting moved over to being a red archetype, cloudbusters are remaining in blue.
Much more mechanized and gadget-centric, Cloudbusters are balloons that typically resembled birds or aeromorphs, they often possess more machine-like texturing and design but also have mechanical components attached to them like air powered thrusters and self-inflating pump mechanisms amongst others.
Cloudbusters primarily interact with objects, including some specialized ones like bottle rockets which serve as hard removal that is played beforehand. And with setups that allow players to recur these from discard, cloudbusters are able to bombard opposing boards, blowing them up and clearing the way for offense.
Cloudbusters also specialize in the float X keyword. Making them effectively untouchable and able to literally go over rival blockers unless they get pumped to size.
Cloudbusters however are a particularly slow archetype, needing time to set up their value engines. They're fortunate to be in a color full of defensive options but cloudbusters themselves have no blockers.
