Here is my team cycle in MP. Each character appears in one team only so you don't have to use recharge or watch ads. I will assume that you have access to all gears (except 3 DOJ ones) and most characters. Target is top 1% (can be lower, suit yourself), and 5000 battle ratings per fight (against EX lv60 gold or E7 lv50 metal).
Turtle strategy is not applied here. You have to win, and win fast. Therefore, Tantu Totem and The Master Death Cart (TMDC) are crucial in most setup. Characters that can chain their SP2 from TMDC's tag-in shots are considered good SP2 carries.
