What about a non-basic attack champ? constriction + pull + assault + carnivorous + spike nova + non-regen selfhealing + some kind of multiplying mechanic
What about replacing Plant Regeneration with: Take Root, Desert Walker, Desert Camoflague? Sandfall would be another option besides Desert Walker.
Hey remember when Varu Dragon had Favor? Can something else have it, some throwaway champ nobody cares about like Wyrmpriest, except not Wyrmpriest. It will be ok I promise.
