BF could possibly utilize this strategy, but part of the power is having a good place to run away to and being hard for people to reach which isn't as big here. T&C can work better but changes making an all out camp match somewhat ineffective. Light Egg Roll allows you to travel the skies quickly and refreshes your DJ but not up B.
I'd like to point out I haven't tested this against all these characters so it's generally theorycraft take it with a grain of salt. Considered with custom option set to off

Characters that are fast enough to possibly challenge us inbetween the tree and the bush:
Yoshi (fast on the ground, as fast as us in the air, rises quickly, up B)
Rosalina (up air reaches really high up)
Wario (bike and good air mobility)
Diddy Kong (Side B and Up B)
Sheik (fast on the ground and rises quickly)
ZSS (Flip Jump, fast ground speed, rises quickly)
Palutena (up smash, rises quickly)
Meta-Knight (fast on the ground, up B)
Fox (fast on ground, rises quickly)
Falco (rises quickly has projectile)
Pikachu (fast on the ground, Down B)
Greninja (fast on the ground, rises quickly)
Shulk (jump monado)
Sonic (fast on the ground, can rise quickly with Up B, Can move through the air quickly with Spin Shot)
Mii brawler small (Fast on the ground, faster than us in the air (wtf), rises quickly)
Mii Gunner (up air reaches really high up)
Characters who can apply significant pressure to the top of the tree from the ground:
Yoshi (can reach with DJ, Egg angles can make perfect shielding difficult, DJ dair pressure)
Samus (Up B can break shields)
ZSS (can reach with DJ)
Falco (can reach with DJ)
Pikachu (Thunder, QAC shenanigans?)
Greninja (can reach with DJ)
Shulk (can reach with DJ during jump monado)
Sonic (can reach quickly with up B)
Generally, if a character has landed on the tree itself they can apply lots of pressure, so you should avoid staying in shield moreso during these circumstances, and either jump away or get under them.
Also worth noting if you are running away don't miss out on opportunity for free damage if they over extend. The greater your lead the worse their morale and better off you are if you happen to make a mistake.
