Hmmm. Does raising stat buff a little help?
I raised the stat boost to +1|+2 / +2|+3. The added HP boost should make it useful as a soft Mass-CC counter. For instance, the unupped version counters thunderstorm and the upped can help counter firestorm card to card... plus it may be a nice little boost to mono-grav otyughs as well.
Could also be nice with Phase Salvagers, since Aether would actually get an in-element way to keep them alive... Which in turn provides a rather nice boost for a certain shield I don't want to name at the moment...
At first I thought this card wouldnt be worth the card slot at all, but it actually works quite decently with 0atk scorpions in monos.
^ That is part of the reason I didn't make the cost lower than it is right now, but if it seems UP in general I may need to buff it a bit anyway.
Also vampires, since this will stack with nightfall / eclipse.
