On Friday before WR, I made 7/10 in Mythic:
😀
But then it proved to be less powerful.
On WR, I tried it and then HRD, and another Mill deck, and ended up in Solar with 9/18 WR wins (starting from Mythic) which isn't bad but not good either.
How much did you spend?
The meteorite version costs $2.69 so expenses for fusing weren't large.
Most of these cards I had fused for another Mill deck I have been playing for a year or so. So most cards paid off a long time ago.
The deck isn't that strong against aggro War decks so I switched to playing my old Mill Deception (the meteorite version costs only $5) which is good against War in all forms except relic War. Enjoying Ethereal Diamond. 8 diamonds, 16 shadows, 6 meteorites, not bad too.
