You should probably work toward a sin demon team using Pit as your Agi monster. A good starter is Pit, beel, abyss, kali, and endless.

With your Agares, you may be able to trade for 3 or 4 of the missing monsters. However, you need to get them all to A+ max and most likely get the pit up to about 5 to 10 agi to be competitive.

I do have a few of these demons I do not use. If you are interested in a trade, let me know. You can message me directly in game. I usually rank around 90 - 100 in overall ranking
