Yoda is for sure the top dog here followed closely by Plagueis then Tenebrous but the problem is Mace. He just doesn't compare to the others in this fight and so Tenebrous would be bale to defeat him in the time Plagueis can give him by facing Yoda. Then the Sith team would overwhelm Yoda and take the fight.
Team 2. Mace defeated a Sith Lord every bit Plagueis' equal, and likely superior and Yoda was doing extremely well against him too. Tenebrous is the weak link here imo.
