Gyarados
I got only one Gyarados 98IV B/C, I only used it for Mewtwo ... and still waiting for the shiny
But now that Gyarados can learn WF I thinking in make it in a Water attacker or keep it and evolve another one.
I can evolve a magikarp with posible IV 89 or 87 (15/11/14 or 15/10/14 A/D/HP)
I have made Magikarp Raids to get a better IV but without good results
What would you recomend me evolve to have two differentes, only TM the 98IV or wait?
Over 900 candies ... dust is not problem

Bite isn't a fantastic move, and Crunch is a downright terrible Charged Move.
For Focus Blast, consider using Gengars (if Psycho Cut), Scizor (for a fast 3-bar), or Dragonites/Lugias for double resistance.
Heck, with Crunch as a 3-bar, you can even get away with just using more Tyranitars or Houndooms, they still do the job very well.
