Strategy for targetfarming aspects ?

Hello good folks .

Since the start of the goblin event I’ve been burning obols on gloves trying to hit an maxed aspect of plains power for my SB (gloves recommended gamble from that site). Also been running a lot of those ancestral undercity keys that the event grants with a offensive aspect blessing with no luck.

Anyone know any other good strategies ? I’ve almost maxed all other aspects but this one is just dodging med hard and it’s getting frustrating .
