2 Kristya will lead to really bad draws sometimes, so run only 1.
Replace her with 1 Genex Ally Birdman.
Compulsory Evacuation Device is better this format then Bottomless.
I would also run Forbidden Lance but you do not have space for it.
Your extra deck needs work, 3 Gachi Gachi is bad, max run 2, otherwise run 1 gachi gachi and 1 Diagusto Phoenix. Your Extra deck needs Sacred Wyvern, Mist Wurm, Gaia Knight.
