I think sergeant strongberry should not get buffed, its the card which singlehandedly carries berries decks and because its too good with every other berry card, every other berry is bad in order to balance archatype out. So heres my ideas of berries changes:
Sergeant strongberry: now his ability says "when any berry besides sergeant strongberry does damage..." So 2 of them would not be able to annihilate everything including oponents health as soon as any damage from a berry is dealt.
Also because the best card in archatype is nerfed, almost everyone else should get buffs
Sour grapes: gains 1 damage and does 2 damage to every zombie
Strawberrian: gains 1 health back and maybe gains team up too
Bluesberry: does 3 damage, gains 1 damage and gains bullseye
Cherry bomb: either gains 1 damage or does 4 damage to zombies here and next door and does 4 damage to a zombie hero
Electric blueberry: looses 1 health, instead of doing 6 damage to a zombie it destroys a zombie and still might do 6 damage to a hero
These are simple but good overall changes, so some berries could be used in other decks besides just berries where sergeant strongberry carries
