General thoughts on mobile:
has felt incredibly powerful off rip, with SD/Protect/Flare Blitz/Close Combat not having much counterplay once setup outside of stuff like healthy Klawf with terastalization, normal/water priority, and Ditto (lol), getting the turn to get to +2 has never been easier as well with Terastalization being around and the tier’s various neutral hits often not being enough to kill it.
got Triple Axel back, so there’s basically nothing that can take its stab combination safely outside of the fire/fightings, Tinkatuff, and I guess Magcargo - all of which drop to Tera Ground. Probably getting taken by PU or NU in January, though.
is an amazing electric pivot - I think it might be too strong for the tier atm but once the DLC wave hits it should fit in. This thing’s fatter than fantom with eviolite and is significantly faster, though it doesn’t bring setup opportunities.
trades Scovillain’s secondary STAB and Chlorophyll access for improvements in basically everything else - great coverage in Psychic and Scorching Sands, the ever useful Knock Off, significantly better Speed, and the ability to run Eviolite to improve its already-better-bulk to new heights. It’s pretty good, but lack of consistent hazard removal could end up balancing it.
is the last mon I’ll talk about here, and it’s really only got a couple options after the mandatory Leaf Storm and Tera Blast (please use tera fire or ground). I’ve been running Eviolite with Knock Off and Glare, though you can pretty easily add Synthesis or Leech Seed as well. Servine can also run Scarf, though that 8 Leaf Storm PP can be quite painful -
maybe you can justify Tera Stellar here, though I truly do think it’s just wholly inferior to Tera Fire/Ground due to lack of defensive utility and the fact that it only hits for neutral - you’ll find it does pretty comparable damage to Leaf Storm’s resisted damage in practice, which just doesn’t cut it when you could be running a coverage Tera instead.
As a final note -
please don’t use Tera Stellar on anything not named Servine, it sucks. It provides zero defensive utility, Tera Blast
lowers your own stats, and 95% of mons that can use Tera Stellar offensively would rather have both different typing and improved offensive coverage anyway. Servine’s realistically the only mon that I would even
consider using Tera Stellar on, and
even then it’s pretty bad overall when you compare it to potentially blowing past Servine’s checks like Swalot and Tinkatuff in one fell swoop as well as the defensive utility Tera Ground/Fire provides for Servine.
