Team 3 triumphs

I can see a strong argument for team 2.

I think team1 is the team most capable in combat, all three have some of the most impressive accolades feats in dueling. However I think I'd still back team 2 instead. Not too sure on Yaddle's standing, but her drawing on the force stronger than Anakin had ever sensed before, and having very obscure knowledge, I think she'd be able to pull her weight. 

Oppo Rancisis is noted to be particularily powerful even amongst the council, again has very advanced knowledge, Bulq was afraid to face him directly, and in a team matchup Oppo is incredibly valuable due to his high-tier battle med. 

While I probably hold Poof the lowest of team 2, he's still also a potent master of battle meditation and telepathy.

The weakest team imo is team 3, with only Koon being comparable to the rest. Ki also could offer a decent amount of competition, but I doubt he's quite on the level necessary to win fights here. Adi is probably the least impressive jedi here

Team 2. Yaddle is straight Yoda tier in Shadow Trap.
