Deebs, Puzzle, and Tyri Pet Battle

Pets to Use:
Mechanical Pandaren Dragonling (1,2,2)
Bone Serpent (1,2,1)
Any other pet, undead is nice here

Open with your Mechanical Pandaren Dragonling

vs Deebs
Just Breath until he dies

vs Tyri
Decoy > Swap to Bone Serpent > Nocturnal Strike > Bone Barrage until he dies
(Tyri always opens with Call Darkness, making Nocturnal Strike deadly here)

vs Puzzle
Puzzle will always open with Dodge, so just pass for your 1st round against him.
Bone Barrage as filler > Call Darkness when available > Nocturnal strike when available


OR

Pets to Use:
Mechanical Pandaren Dragonling (1,2,2)
Rapana Whelk (2,2,x)
Any other pet, undead is nice here

vs Deebs and Tyri
The basic strategy is to just use Thunderbolt when it's available and Breath until your Dragonling bites the dust.
Swap to Rapana Whelk, keep Shell Shield up and Absorb as filler.

vs Puzzle
Just keep using Shell Shield and Absorb as filler.
It's highly doubtful your Whelk will die, but any 3rd pet will be able to finish off Puzzle at the end. I prefer undead since Puzzle is a humanoid and undead perform well against them.
