Pokemon Reborn Cynthia Challenge Part 22(Elite 4 & Champion)

Reborn admin Amethyst invites Sinnoh Champion Cynthia to fix the team Meteor problem. Cynthia's new journey begins...
This moment finally comes. Our team is surprisingly close to Cynthia's Platinum team, with only Milotic being replaced by Glaceon. Glaceon runs 252 Sp.Def and 252 Spe and we will use EV tuner to replace Speed EV with HP EV later on.
Glaceon and Garchomp beat Heather through Z-Celebrate strategy that gives user +1 boost on all stats. Garchomp holds Wide Lens to prevent Rock Slide miss.
We continue using this strategy for Laura & Bennett, but we need to change the weather to neither the rain nor the sun, so Hail is our option. As you know, the best way to counter Flower Garden field is burning it down, and that's also what we do here. Again, Wide Lens on Togekiss to prevent Heat Wave miss.
Z-Celebrate isn't a good choice for Elias because of his Ditto, the traditional reverse sweeper, but we find out Choice Scarf is especially good in this battle, so we give to Garchomp and it destroys Elias with mega-Lucario and Togekiss. Togekiss can be switched in when Ditto transforms into mega-Lucario and locks in Drain Punch.
Anna doesn't have much to talk about, since Z-Celebrate mega-Lucario totally destroys her. Meteor Mash is further boosted in Starlight Arena, making +3 Meteor Mash OHKO Starmie even with Aurora Veil. Drain Punch is better than Close Combat for mega-Lucario sweeper set.
Finally it's time to battle with Lin. All her Pokemon have PULSE2. We setup Z-Celebrate successfully, but Lin having Conkeldurr means we cannot Baton Pass to mega-Lucario, so we choose Garchomp instead. Garchomp takes down half of her team, but it has to lock into Outrage to deal with opponent Garchomp. We both have 1.5x speed but Lin's Garchomp has Adamant Nature while ours has Jolly so we outspeed her. Lin sends out mega-Gardevoir to take down Garchomp but it is a prey of mega-Lucario. Spiritomb holds Assault Vest and runs 252 Sp.Def to handle Delphox after Earthquake damage and PULSE-Abra successfully.
The second Lin battle is kinda anticlimax when we only beat her with Glaceon and mega-Lucario, showing that what kind of powerhouse mega-Lucario is. For the third Lin battle in Anna route, we can either Toxic Arc-PULSE to death, or trade it with Destiny Bond. It turns out Roserade doesn't involve in all these battles, but considering how it carried us through all the previous chapters, it deserves to have a spot in Hall of Fame.
This challenge doesn't end here. Tomorrow we will begin to upload postgame battles and they are as interesting as those in main game.
