Free Feathers Defense Team

You could probably keep everything execpt the weapon on, idk how much that affects your score (albeit alot but not sure). Or first stage weapon like iron sword, axe, etc

If you put a unit that's really bad people will generally think that you're trying to bait them, so maybe try a strong-ish unit like either Corrin (either one), Palla, or Anna. Anyone from the starter squad (Anna, Sharena, Alphonse) will also do the job,

Just run a mix of fully si infantry(villagers)/dragon/flying/armored units (no mages/ archers or horses). They have solid base stats and they should be easy to pick off or bait. Preferably with legendary weapons like sherena and with area specials/aether/galeforce.
Malachai is the perfect example. He comes with an aoe skill, a legendary weapon, iotes shield and has an ok bst.

Another idea is to give really good units uselessl/suboptimal skills. Esp for amored emblem. Like give hector refiant res instead of distant counter

I've tried to give people free wins by throwing together an all-sword team with only a few of them even having SI, thinking no one could lose. Sadly...several people including some with perfect-IV SI Lindes showing have lost to that team.
So now I'm generally too lazy to switch since it seems like I cannot stop people from losing.

You're too kind x)
