When Wolves (and subsequently Dogs) get implemented I hope we get to make their decks starting with the basics like fell scratch/bristle. They could learn moves by fighting animals with us, and it could learn certain moves from certain animals, such as Roar of the Wild, Chomp, Vampirism (bit of a stretch), and Sudden Charge. Stats would be determined by food that you feed it to increase them, along with breeding them to determine the stat cap/run speed/scent following etc.. While taming wolves you could get different breeds by introducing them to different stimuli and foods which would determine some base stats of the animals, such as Bloodhounds being strong/slow/top level scent tracking while Labradors being Mid-Strength/Mid Speed/Mid tracking (not what the actual stats should be just examples).
Just some ideas. Any funny troll moves they could learn?
