How I think this idea should work, if/when it is finally implemented:
Consumable item: Technical Machine -- Randomly change one or both of a pokemon's moves. (Can't get from pokestops. Can only buy through the store with coins. Change to a different available moveset. Could change the fast move, or the charge move, or both.)
-- Maybe also cost a number of candy related to the egg distance of the pokemon and the evolution costs.
On related point, I think Lapras should have a water charge move instead of Dragon Pulse. Both of its ice charge moves already serve the purpose for attacking Dragonite. One of the closest things to a Lapras counter is a fire pokemon like Arcanine since fire resists ice, so it would be nice if Lapras had a water move for type coverage like most other pokemon. Out of the current water charge moves in Pokemon Go, in the main games Lapras can learn Water Pulse, Brine, and Hydro Pump by leveling up, and can learn Aqua Tail by move tutor.
This is sorta why I don't think they would allow for this change to happen...There would be less need to grind for more incubators/hatches, etc....meaning less money for Niantic...if they allowed move changes.
Most people still keep playing to get better moveset or higher IV mons and allowing a change of one or the other means less reasons to keep playing.
Don't feel too bad, my first Lapras hatch had the same moves (Ice Shard/Dragon Pulse). I have maxed it out for my level though and plan to keep powering it up...
Yours is at least 98% so I'd be super happy in your shoes.
Wife upset having played for 4+ months and still no Lapras (I have 2).
What if it required half of the evolution cost to randomly reset a 'mon's move set? 50 candies to reset Dragonite's move set. 1 in 6 chance of getting your ideal move set? 25 candies for Rhydon with a 1 in 6 chance to get your ideal move set? (My first 5 caught/evolved Rhydons ALL had Rock Smash/Megahorn).
For those wish no evolution (Lapras, Snorlax...), it would have to go to the highest candy cost (50 candies)? Just a thought. No guarantee, but at least you'd have a chance at salvaging a high IV 'mon with a terrible move set. Nothing is worse than a 'mon with 93+ IV's, a garbage move set, and no hope of being able to put it to use.
