It might be if the odds of Garnet even being alive to toss out a summon weren't so slim, given the kind of assumptions Piggy's team needs there. The more I look at it, the more I think that Lucario and Char just drop Garnet and now the team is over. Ness gets a turn by them killing any of Chemist or Garnet outside of Orlandu getting a doubleturn on Ness (which I have to add, is mathematically not possible even to my scaling of TB-speed buffing, which is just about as generous as it gets for TB scaling in general). Since Venusaur is also faster than both Chemist and Ness, since he hasn't been even looked at, he can just status any other possible factor in the fight - including Orlandu, who's forfeiting blockers if he wants Ness to die before he gets a turn and has failed the proposition if he picked even one blocker.
