I think Srgt. Strongberry/Srgt. Strongberry is the reason why berry decks are as popular as they are, however popular that may be. It seems like it would be pretty easy to eliminate the feedback loop by wording Strongberry such that it cannot refer to damage dealt by itself (or another Strongberry).
On the other hand, I’m used to Magic where infinite feedback loops are rampant... and I also have a RNG Control deck that finds Berries ultimately way less scary that Cyclecap, as well as a Z-Mech aggro-control deck that eats berries for breakfast but fails to Rose 90% of the time (I’m guessing... I don’t keep stats). So I’m not too bothered by this meta.
