my 2 pet strategy starts like the strategy listed above, except for the second pet i use darkmoon zeplin. when your 1st pet dies switch to zepplin, use decoy then rocket until her last bird is at 620hp or less, then use the explode talent. your carry pet gets the exp.
yuo need to make sure that her last pet is not going to use her heal or take-off ability on the same turn you explode, pass if that is the case.
this strategy works 4 out of 5 times, ocassionally rng gets the best of you though.
your carry pet will need about 500-600 hp to be sure to survive the tornados.
with the safari hat on i am getting about 2800exp iirc, compare to about 4800 for pandera or wod trainers. so not great but not terrible. ive been doing it every day for about a month now with no luck on the albino buzzard. ive had 3 class specific quality upgrade tokens drop (all for classes where all my pets were already rare quality though).
sorry for the lack of detail and poor writing, im responding to this via my phone and am going off memory. if its not clear enough, pm me and ill fix it when i get home
