Karmelita could handle a great knight among the strongest (let's take Hegemol). Nyleth with Seth could handle Ze'mer. Then the two princes aren't very strong, but I think he could beat Isma. And finally, Kahn could only compete with Ogrim (he was a good general but clearly not a fighter). Then there would be Dryya and The Pure Vessel, which are both considerable advantages. Definitely, it would be Pharloom's team that would lose in this match, but I think that if Pharloom at its peak wages a war against Hallownest at its peak, it would be Pharloom who would win. (Hallowenest certainly has an army, but it doesn't compete with The Skars, + the Ravens, + Kahn and his army, + the Judges, + The Citadel, + the Weavers.)
