Beast Battler of Khaz Algar

I used Bucktooth Flapper (1,1,1) and Spiketail Beaver (1,1,2) plus a Flat-Tooth Calf (2,1,2). They all have their 1st slot with an attack strong against Elemental. It took me twice, but I just spammed 1 on all of them and got it.

Also, you do NOT have to wait for the world quest to come up to work on the achievement. You can repeatedly do battles with the other teams when she these are up, even after completing the world quest.

Hippos are your friends (search your collection for 'Calf'). Spam Water Jet and use the Clobber (stun) ability when Stratus is lining up a big attack, which will force them to swap out. Your hippos should be faster than 276 speed.

Easy. You can pretty much take any 3 beasts.
