Reminder: Shadow ZA starters with Frustration can get their elite moves via normal Charged TM during this event

I realized I forgot to TM Frustration off of my shadow Tepig last event, but remembered that Blast Burn is TMable for the duration of this event. Second moving the mon allows you to circumvent Frustration and TM into Blast Burn after you've evolved it all the way up. Save yourself an ETM!

Edit: tutorial to clear up any confusion.
Assuming you have a Shadow Chikorita, Totodile, or Tepig currently with Frustration:

1. Teach it a second charged move with the option at the bottom of the summary screen
2. Evolve it all the way into its final evolution
3. Use a Charged TM on the second charged move until you get Frenzy Plant, Hydro Cannon, or Blast Burn in that second Charged Move slot.
