In mid and big gowen files there is barely room for sacrificial units like salamander and adding them is a waste of lp. Also you often can waste your attack power unnecessary on lvl1 sacrificial units like whisp, buncle, and others. To meet this issue gowen has a couple of low cost grims that kills such units like fire breath or gaia fang.
Just recently you buffed gaia fang by adding owl under its targets.
Yet a new possible target came across for these grims and I have issues to understand why it doesn’t fall under their range: Obsidian Carbuncle .
I think this card should fall under the range of these grims, especially now that you release a falkow unit like EX for this subtype(pinpoint dmg, agi control) .
My suggestion: either
A buff those 2 grims by making them ignoring def (arguably a bit too much for a lvl1 grim)
B Take that 10 def away from obsidian. Considering what role this card have that defence is counter intuitive anyway.
