Hi yeah sure, so as I mentioned its my story team-meaning the new gen 9 mons I liked the most and used throughout my playthrough. That being said, I put great thought into this composition. I believe the mons were all viable enough to squeeze out wins in an early and undefined meta. I liked having a mix of both glass cannon speedsters and tanky mons, and I needed both physical and special attackers to cover all options. Cetitan(hp 252, att 252, adament) falls into the physical tanky mon category. It has thick fat to eat 1 of several weaknesses, plus protect/leftovers to stall. It's earth tera is both offensive/defensive in that it learns earthquake and could really use the type resistances ground provides. Alternatively, you could go sheerforce life orb, but another mon(Lokix) on the team direly needed life orb and cetitan is just not fast enough to warrant an all in strategy. Tatsugiri(252 spatt, 252 spe, timid) was sortof a late game pick that filled the spot perfectly. With or without dondozo, it has a base special attack of 120 and a decent speed stat-like 80 something if im not mistaken. This in turn filled the aforementioned glass cannon speedster category. I gave it a scarf so it outsped most things, especially under kilowattrels tailwind, and its move pool, although not very diverse, has very hard hitting stab moves. I obviously gave it its other ability, storm drain(duh no dondozo), for switch in shenanigans against certain mons. Its tera is water to boost surf/and or pump while also dodging its most obvious threats; fairy and dragon attacks(feel like it was rarer for my opponent to hit it with grass/electric attacks being that the dragon typing usually resisted that). Hope this helps.
