yes, ai4 has gotten better, like 10%. this deck was for 1.27-28. I use it with upped shields and it works like a charm. Try to farm ai3, once yo uget electrum, upgrade a shield. IT HELPS ALOT!!!!! if u having trouble, change mark to earth, add 6 protect artifact, 5 immortal, 6 shields, 4 dragons, 9 pillars. or -2 immortal for +2 pillars.
