You have a guaranteed 50% free magic resistance from the Orb of Lusory on that dungeon. Once you know that, you can look for it then start regen fighting really high level Warlocks, Animated Armours and the like. I went with Taurog, knowing that elf would keep me above 6 mana, then I could always Bloodtopowa/Burndayraz down Tower of Goo if he turned up.
Otherwise, I don't really rate Tikki Tooki on this dungeon in particular - Illusions and Golems are both unusually tough popcorn and the free MR makes getting hit repeatedly by higher level monsters very attractive.
