A “bit bulkier” might be a stretch when looking at raw bulk.
252+ Atk Tera Water Mew Wave Crash vs. 0 HP / 4 Def Chi-Yu: 428-506 (170.5 - 201.5%) -- guaranteed OHKO
252+ SpA Tera Water Mew Surf vs. 0 HP / 0 SpD Chi-Yu: 230-272 (91.6 - 108.3%) -- 50% chance to OHKO
252+ Atk Tera Grass Mew Wood Hammer vs. 0 HP / 4 Def Kyogre: 390-462 (114.3 - 135.4%) -- guaranteed OHKO
252+ SpA Tera Grass Mew Energy Ball vs. 0 HP / 0 SpD Kyogre: 204-240 (59.8 - 70.3%) -- guaranteed 2HKO
But consider the following;
-Chi-Yu with its resistances is too bulky and fast for how much power is behind its special attacks.
-It has pretty important resistances like Dragapult’s Shadow Ball, Rillaboom’s Grassy Glide, Make it Rain and Shadow Ball from Gholdengo, Kingambit’s STABs, Torch Song from Skeledirge, etc.
-It has Choice Scarf sets which outspeed everything besides Deoxys-S with even Modest nature, and even then can use Boots + Web support
and most importantly
-Both are obviously broken despite having flaws that aren’t detrimental enough to make them worth considering for a drop
the most consistently well-performing mon in the entire franchise (bw doesn't count) for a reason. high spa, powerful stabs, reasonably fast, and decently bulky, especially with its unique defensive typing. pairs excellently with the still-strong balance core of glowking and ting-lu, though it now faces stiff competition in this role from skarmory. static is excellent for punishing contact moves and will stop sweeps dead in their tracks with just a little sprinkle of luck. matches up well defensively into top-tier mons like great tusk and zamazenta and offensively into enamorus, kingambit, gholdengo, great tusk and zamazenta again, pex, dozo, hamurott, volc, skarm, and a host of others. has consistently been a top-10 mon in this gen in the last two metas and will likely continue to perform, though raging bolt and skarmory compete for teamspace as an offensive electric-type and a defensive flying-type
a very solid mon that's historically performed quite well this generation. boots let it come in on hazards to keep multiscale intact, giving it plenty of opportunities to set up a dragon dance or two and start sweeping. tera normal espeed is some of the strongest priority in the meta. i expect its viability to suffer a little in this dlc, though, because there are several more options against it—skarmory walls the eq/espeed/roost sets all day long and can phaze out the ice spinner sets before they threaten it too much; icicle spear kyurem and triple axel weavile destroy it through multiscale, forcing it to tera early if it wants to survive; volcarona and roaring moon are back to threaten it with burn and the occasional scale shot; basically every relevant new dlcmon threatens it on switch, except gouging fire, which threatens to burn… this dlc was really not good for dragonite, but i still expect it to have a place here when all is said and done
almost completely outclassed offensively by its hisuian form, which can do every meaningful thing the kantonian form can plus fling insanely powerful dual stabs with no recoil, and has a little more attack to boot. defensively, though, it's a bit more interesting since it isn't shackled with a defensively hideous rock typing. intimidate, will-o-wisp, decent bulk, and reliable recovery in morning sun make it a potential niche pick as a defensive fire-type, but it has to compete in this role with gouging fire, moltres, and occasionally volcarona, all of whom just kinda do the job better while offering more offensively. the pure typing and intimidate are interesting, though—i could see this being a microniche mon
i hate to say this about someone's favorite mon, but unfortunately, i don't think blastoise has any role in ou. it's outclassed as a bulky water-type spinner by tentacruel, as a bulky water-type shell smasher by cloyster, and as a bulky water-type in general by a bunch of other pokemon that people actually use. it doesn't really bring anything unique to the table that can't be done better by something else
and maybe an intimidator? Sinistcha is decent (I guess) as well, and/or 
?
