Coded Ice Titan in layer 30 (btw probably my last request for help in Re:Coded xD)

so im pretty worried im not gonna be able to own Ice Titan, i got pretty destroyed the first time i fought him and i think i only took out 1/4 of his health. advice?

 

First I did the Ice Titan when I was Lvl 50-60 (can't remember) and I just used the ATK up, DEF up, regen, auto life (each work for about 6 rounds except the auto life) and I just used combos from my deck that dealt the most damage. Oh and timed the attack and defend buttons. Hope this helps, and good luck!
