It is the fastest recorded unupped AI3 grinder.
That may fastest unupped deck, but it costs 1800

. If the goal is to get first ~10k

, I wouldn't waste that much for it.
My suggestion is mono

Adrenaline rush: 12 Pillar, 6 Frog, 6 Cockatrice, 6 Adrenaline. Costs only 740

and is only little bit slower than that^ in AI3 grinding.
According to the stats made by "thenewguy" and "willng3", it would take around 17 hours to grind for 10k +"the price of used deck"

with any of those 2 decks.
