I don't see how this is possibly any better than straight up death rush (4 drag, 6 mummy, 6 poison, 14 pillar). It's far slower and doesn't really contain enough defense to outstall a death rush.
Using simulator,
Player 1 [Your deck]
Wins: 49
Winrate: 4.9 %
Average TTW: 9.551020408163266
EMs: 0
EM rate: 0 %
Player 2 [Normal death rush]
Wins: 951
Winrate: 95.1 %
Average TTW: 8.121976866456361
EMs: 0
EM rate: 0 %
Of course the AI isn't very good with this deck most likely, but 4.9% winrate against a normal death rush is strange.
