lots of tribes

each tribe has own rewards which you get when you beat them

better rewards from tribe the further in tournament you go

tl;dr dont fight the tribes you want the best rewards from (example -> +1 projectile tattoo means you want ramako tribe in final rounds)

fieldmaster from kahuturoa = op on flank

flank = main way to beat enemy team so its priority

escort is second best

attack third best

defence is meme, just extra space to put stuff on last during final rounds

strategy = dont get hit, especially while channeling enemy totems, can use minions/totems/slows/etc to help keep enemy team cc'd (nerfed in latest patch but still best thing to do at high rank), let flank and escort do most of the heavy lifting (escort will follow you so its good to play aggressive sometimes)

extra tips = you can sell consumables and units to other vendors for half price eg: sell a unit from any other tribe to  kahuturoa to buy more fieldmasters :^)

also recommend taking out kahuturoa tribe from the tournament early by elimation (fight kahuturoa tribe in round 2) because he can spawn a titanic turtle which is bugged and can become nearly invincible

worst units to deal with IMO = goliath/spear dancers/storm conduit/kahutoroa captain/maata captain

best tribes to keep alive until final round = ramako/tawhoa/ngamahu/rakiata
