I have a Dihada deck too, though I'm having a few issues making it consistent: when it works, it's pretty good with a ton of lifegain etc., but it doesn't have a consistent game plan besides playing Dihada and +2ing on one creature. Mind sharing your decklist?
I play Dihada as well, legendary tribal, instead of just a turbo reanimator or just for the treasures. It is a very resilient deck, and added the Godo/Aurelia + Helm of the Host combo to help me finish games.
