Completing DIM Adventures on the VBBE

Has anyone been able to successfully complete any of the DIM Adventure Modes on the Vital Bracelet BE? I've been stuck on Stage 12 of the Impulse City DIM, with my Kazuchimon (VA) losing to Achillesmon (VI) 3 times in a row, even with type advantage and at max Vitals.

Edit: FINALLY got past Stage 12 and then steamrolled through 13-14-15 to complete Adventure Mode and unlock Shroudmon. Thanks everyone who commented!
