Partly so I can easily remember, and partly because I want to share how I defeated the trainers.
Burning Pandaren Spirit – Townlong Steppes
Rapana Whelk to counter Pandaren Fire Spirit
Anubisath Idol to counter Crimson [Dragonkin]
Anubisath will likely be able to face off against the third Glowy [Flying] as well, depending on luck but any dragonkin in the third spot would be good or a Flayer Hatchling
Flowing Pandaren Spirit – Dread Wastes
Disgusting Oozling is immensely effective against the first two – Marley [Aquatic] and Tiptoe [Critter]
I usually tack on both the Anubisath Idol and the Flayer Whelpling to pick up when the oozling dies.
Whispering Pandaren Spirit – Jade Forest
Deathtalon Whelpguard to counter Dusty [Flying]
Anubisath Idol to counter Whispertail [Dragonkin]
Lil Tarecgosa to counter the Pandaren Air Spirit
I usually only need two of the above, but I have the third just in case
Thundering Pandaren Spirit – Vale
Dancing Water Skimmer to counter the Pandaren Earth Spirit [Press Pump 4 times and he's dead - first press amps damage, second hit him]
Egbert to counter Sludgy
Flayer Whelpling to counter Darnak the Tunneler
Egbert usually survives long enough to do a little damage to Darnak and eat his first burrow.
