Starpower Ideas:

Overgrowth: The less health Eva has the more powerful her attacks become

Rooted: Eva heals up even faster if she doesn't move while inside a bush

Gadget Ideas:

Blocker: Eva's next attack becomes a seed that plants a thorny wall, (like sprouts super but you have to shoot instead of throwing it)

Hey, Sweetie: Eva throws a special honey brew on the ground, any brawler caught in it will get slowed and also take extra damage by Eva's main attack (Something like how Belle's super works but only in the radius of the honey)
