The big problem is: you´ve got 6 creatures, any CC deck will kill them right off. And, if you use this deck to farm ai3, I´d suggest the following:
-2 Improved Healings
-2 Jade Shields
-3 Forest Scorpions
+6 Giant Frogs
+1 Jade Staff
or
+4 Giant Frogs
+2 Cockatrices
+1 Jade Staff
Maybe this would even work with only 10 pillars and you could add another scorpion
