Dragons!

This is part of the Family Familiar achievement.

I'm creating guides for all trainers for you to follow easily. Displaying 15 different strategies here would be rather confusing, so here you go:

No idea how successful this tactic will be for others as it worked on my first try. Definitely some RNG elements like Cyclone not hitting and wasting Howl at the end. Others that are better and smarter than me might be able to improve upon this tactic. I didn't look particularly hard, but it seems like most other tactics requires Yu'La, or duplicate pets, so this is what I came up with.
