Its gonna be like the other dokkan events of needing specific characters with the Link Skill "WE GOTTA POWER", without those characters it'll be near impossible/big pain/DS spend time.

There will most likely be a new summon Gasha with the PHY Buu and other Buu Saga characters with the link skill. Your best chance is to save DS for that Gasha if you dont have enough of those characters.

And personally I only play the Tree of Might event to get a lot of the Tree of Might awakening medal to sell to Baba lol. The characters are very useless unless you simply have no one else.
