I've found that lotus eaters are great against anyone that makes markers. (Parker, Titania,Mei Feng, etc) the other thing they bring is condition "immunity" for the cost of a chi. Great against condition based crews (Tara, kearis, daw)
I usually use 1-2 archers as ranged threats usually not bringing samurai while there good I like that you can give archers fast and other effects since there monks.
High river monks I find are good solid beaters. While there damage track seems low, the stat 8* with burning and flurry helps rack it up. They also have ruthless and a good zero action Push 3 and focused for 1 damage ( Which I believe with sensi Yu gives you a chi too)
