Gardevoir’s use in the meta?
Answers
Yeah, Machamp is a fascinating mon for this kind of challenges. The only problem I have is that I'm reluctant to use stardust on anything that's outside of normal meta, because I'm not exactly swimming in it. Even Gardevoir, I only powered it up to L33.5 for just the right TTW with its IV. The rest of my 6U-NL team are mons that are still useful for gym defense or other things (C/Ps Eggy, ZH/Ps Metagross from before CD, Hurricane Dnite, etc).
I sadly started to move away from T3 solo to T4 duo challenges, because the best friends bonuses are just too good. I do this only during weekends, as during weekdays I just do T5 with my raid group.
On defense, shove it between any two of the normal type tanks and hope whoever's attacking isn't just plowing through with a MM Metagross.
On offense, it's a go-to choice for fighting type raids and a high TDO option against dragon type raids should you wish to avoid re-entry. Just keep it away from Machamp that know Heavy Slam.
