Dragon Ball Legends, PvP Game: World Tuornament #1. How to win agains Ultra Janemba?!

The second time, I won against Ultra Janemba. Then, the third time was in the Treasure Battle.
Taktik:
1. If Janemba has in the Battle Full Boost, then you can just attack with a blast attack. If not, then you become an Ultimate Attack directly.
2. If you fight with a nother character, then try just attack only with the blast attack, or you risk the cover change, and you become an Ultimate Attack again.
3. It can be that you should to sacrifice one character, for that reasons it's good if you also have a red character in the team, such as Ultra Vegito or, for example, a Switch Character (like the androids)
