The problem is that there are many effective grinding decks, and no one will make a SoV based deck if it's not proffitable against arena and FGs.
This card doesn't improve stalling, so doesn't help to stall againt FGs and platinum
great creature spamming decks.
The only way to use this card effitiently is making a rage quit deck with 6 SoVs just to finish it before the oponent decks out.
That's why, children, 95 out of 100 SoVs are seen in platinum ragequit decks.
I have seen many with other 12 SoSac. Lucky me that I'm using my 200HP OTK
