Have you tried looking at sites like edhrec.com? Also I think an Intruder Alarm could help greatly.

I agree that the EDHREC page for Kraj is probably a good place to start for general ideas. Also, here's a Scryfall search for every card with "untap" in your color combination, sorted by EDHREC popularity.
