here is a tip but can't get the team killed yet cuz of luck and my sup sucks;
First i switched to a 3 1 1 formation, yoru, momo lvl50 (wich sucks!! and dont have harribel) and urahara: main and koma
1v1: i use skill 1 title eagle eye and zabimaru; 60% win my hit lvl is 186
5v5: i use skill10 and jizo as zanpakto : yoru stun the sup and momo stun one of the assaulters; also
Can somebody tell me what's left;
I'm lvl89: BP 410K
