I frankly hope they do what I suggested in another post, in short:
  1. Kaiten coming back, but giving Direct Hit instead of 50% Damage, thus rewarding Resource Management
  2. Tsubamegaeshi being rolled up in Iaijutsu, just how Ogi Namikiri is right now
  3. Ikishoten turning Shinten to Senei and Kyuten to Guren as a Trigger (Credit to xAFROx for the suggestion!)
  4. Tenka Goken as Cone AoE again!
