Have we tested the earth duo against likely fire decks since we made the alterations? If the results haven't changed materially I think we're significant dogs against their range. Maybe we should consider a fractal deck instead?
Starting next round we face aether only. Every match for the rest of War. So I agree we need to keep some cards hidden; Team Aether does its homework. And on that note dragons will be les useful going forward against potential lightning. That said, I'd hate to eliminate any dwindling creatures.
If we have no critters hiding in the vault and (for instance) our fractal decks are our only winners, we have six creatures to divide among next round's decks.
If we're going to test the earth duo, maybe we should consider slimming it a bit to make room for RTs, steals, etc in the vault.
Thoughts?
