Dragonite is actually pretty good. Has all of the tools it needs to set itself up. 3 Altaria and a choice band puts you to 160 for L. 4 takes you to the 180 mark for L. With a good one attachment, and one basic attachment at that attack, you can abuse max potions and your 250hp all day.
That, and if you Zinnia, you can get a Giga Impact in one turn if you have L/W in hand. Could even use something like a professor's letter to get them and Lele for Zinnia, order pad is a potential, though janky way to increase the chance you can have one on a given turn. Or better yet run Ribombee if you have the bench space.
Zinnia is also very good for Noivern which got the buff with the normal type Noibat. Noivern/Garb is actually on the table now imo.
Kyurem is a disappointment of course, but Dragonite went better than expected!
