Honestly, I'm not a fan of putting Terapagos teraing and every other Pokémon as literally the same thing. Besides the name, what Terapagos does is simply not a universal mechanic. The universal mechanic of Terastalization allows you to choose any of the types available in the game, changes your type, and boosts the power of the Tera type. The universal mechanic of Terastalization does not make you change your ability, give you +100 BST, and quite literally changes you to a different forme of the Pokémon, with no option of changing what type you want. It is a unique mechanic to Terapagos that just shares the name with the others - and in a VERY relevant way, not something minor like Dynamax vs Gigantamax. Held items are also a universal mechanic of the game, but we still banned Gengar from holding Gengarite, not Gengar from holding items, Gengar, Gengarite, or Mega Evolution, or holding items in general.
I do plan on making a Policy Review thread on Terapagos-Stellar since I think the metagame discussion thread is not the best place for it - there's tons of stuff relating to the actual meta to talk about, alongside the fact that this is something the goes beyond OU and affects Smogon in general - remember, base formes weren't separated from Megas initially until ORAS where there was a Policy Review discussion, as Charizard was also attached to Mega Charizard X and Y, so base Charizard was OU and couldn't be used on lower tiers. Terapagos has similar cases for us to compare, but no one-to-one comparison, it's simply a case of its own.
Accurate rock stab, cc/eq coverage and excellent speed makes iron boulder a great booster sweeper. It's typing isn't great and it gets bitched by kingambit, but once it gets an SD it can rip teams apart.
Gouging fire has the perfect stat spread for a dragon dancer and is a big threat once it sets up. Crazy damage output under sun, and great synergy with walking wake. Flare blitz is kinda risky to rely on for its main stab, but it gets morning sun which helps. Probably the best new paradox pokemon.
I've had a lot of fun using raging bolt, it's slow but electric sucker punch is great. I've been running sub+cm which takes advantage of it's great bulk. It doesn’t have good coverage, and it's vulnerable to fast dragons that resist thunder clap, but it still fits in quite well in ou.
- buffed Luster Purge and Flip Turn are both really nice for it, and the meta is just nice for it considering it kinda switches into Tusk and threatens it out, completely ignores Spikes without boots, still has recover for longetivity, and has wide potential set variety, and unlike many Psychics & Dragons can threaten an OHKO on Gambit, I can see it having a shot at staying OU this gen - i think Pult is still probably the easier mon to fit but Latios has a potential niche, i think :)
is so fake that is doesn't even deserve a mention :P also gouging fire can effectively use heat crash because it is a chonker; weighing in at 1300.7 lbs or 590kg. imo iron crown is pretty ass cuz it's mid overall, but ig u could go with scarf, double dance (pick from agility, cm, or id), and u could also use booster, however, crown has 0 coverage.
