10 New moves, battle teams and more

What if Crunch and/or Outrage become legacy, and Hydro pump stays?

Outrage can work for attacking Dragonite if you have nothing better. Crunch can be used against Psychic pokemon with fighting moves (Mewtwo, Alakazam). I think Outrage is the less useful of Gyarados' available charge moves, so that would be the one to change if you were to use a Charge TM.

I think the chances of Hydro Pump changing are low, but worth considering. If it is removed, it would be very likely replaced with Aqua Tail, so not a huge loss but not the strongest possibility you could have had.

It is much more likely that either Dragon Tail or Bite is going to be removed for Waterfall. At the very least it would be worth a fast TM to change your second Gary to B/C to have as a backup dark attacker.

Without the 'pay-to-win' customers contributions, there is no high and mighty free players to look down on those willing to pay their way - as the game wouldn't exist.

Infinitely more desirable than lucky eggs, though. And you still have to put in the effort of catching as much as possible during that 30 min window for it to make much of a difference. Though I'd personally much rather they had introduced a stardust berry like the Pinap.
