Quite a few noms, some parroted from other posts, gonna be a bit of a long one.
T3 -> T2
I'm inclined to agree with Eragon on raising this one, this thing gained a LOT after home dropped, with almost all forms of priority blocking falling out of favor in the tier, it's become one of the top 5 mons for me. It's had a dominant run on a number of screens teams, finding a home alongside
and either
or
as an incredibly bulky Water/Grass/Fire core, especially abusing grassy terrain and fake out support from
to set up and become incredibly diffcult to remove under screens. It matches up very favorably into the big threats of Flutter, chi yu, and Chien pao, hitting them all extremely hard and not being particularly threatened in return, and not bulk up drain punch sets being particularly walled by anything in the tier after a few boosts aside from Basculegion. An argument can be made for tier 1 but I'm not fully sold on this mon being universally applicable to any team, unlike my next nom.
T2 -> T1
This mon may have lost grassy glide, but it's still the king of being a bulky pivot that can threaten and annoy nearly anything. As OSDT has continued Rilla's been seen on more and more teams; reaching a 33% userate in week 2 with no signs of that number decreasing soon, being an absolute staple on balance and bulky Offense for its fake out support and grassy terrain healing. It can be a menacing bulky backbone of a good few hyperoffense teams that greatly appreciate it's pivoting, fake outs, and absurdly strong wood hammers that can demolish mons like
and
that may otherwise pose problems for such teams. I've even seen it on trick room team, who appreciate it for the aforementioned reasons and it's valuable grass typing to block sleep from
while being able to easily generate momentum for its partners off a switch in. I can't see a real reason not to run this pokemon on any team as glue right now given its sheer dominance over terrain setting, great offensive, supportive, and defensive profiles and access to moves like taunt brick break u-turn fake out and the now rare knock off that always allow it to perform and compress a number of roles for its team.
T3 -> T2
A terrifying late game threat that also offers strong wallbreaking and revenge killing in the mid-game, Basculegion's seen use on a number of teams as a terrifying presence that demands respect in the builder. Scarf, Rain, and even AV sets make use of this mons fantastic offensive typing and moves and it's solid bulk on a wide variety of teams that I think make it worthy of being T2.
T2 -> T4
Only really seeing use on fanroom, bundle is a shell of it's pre-home self in the current metagame, unable to adequately threaten many common mons, and being far less effective at speed control with Tornadus and Cress around.
T5 -> T4
A very competent trick room abuser that I suspect will be more prevalent in the wake of
's ban as a bulky behemoth that can get out of hand if not played around right.
T4 -> T3
A real standout on Hyper offense, balance and hazards for it's raw damage output, great matchups into common speed control mons in the tier, surprisingly fantastic utility movepool with the option to set rocks, abuse STAB u-turn, set tailwind, and even abuse feint on AV sets to ruin many a protect play. A great mon that can fit on a variety of teams with Scarf, sash and AV sets and a good bit of potential yet to be seen that may yet take it even higher in the future.
UR -> T5
This thing is a surprisingly competent hazards spammer, with access to taunt, haze, memento and intimidate to halt many forms of progress opponents may try to make against it. Its outstanding typing and eviolite give it surprising bulk, making it a valuable switch in with intimidate and barb barrage gives it a means to hit the ever-increasingly common grass teras in the tier and Rillaboom for decent damage, especially if the target's already poisoned. A mon with a very solid niche on hazards stack teams but ultimately fails to see much legitimate use outside of such a strategy.
T4 -> T3
OSDT has shown that Gambit is still a very potent threat, both under trick room and screens teams that even a balance team made it to the
sample list.
T4 -> T5
While tera seems to have boosted this mon even higher than last gen on paper, the reality is that it's almost entirely outclassed at any niche it may wish to perform by the ever-present
, who abuses tera better, does more damage, and has the potential to be in a faster speed tier.
and
invalidate it outright in many situations at speed control, or even icy wind
and the lowly
for such a role, it's bulk is nonexistent and with so little priority control in the tier now, that really hurts it. There's overallvery little reason to use this thing outside of being a decently hard hitting fast electric type attacker into the many waters and flyings in the tier now, but even then many common metagame threats can outdo it with their own neutral hits
UR -> T5
A very competent tera normal espeed abuser next to pao that can offer much more powerful hits over alternative options to strike with thanks to rock head flare blitz and head smash that from my experience gives it a useful niche over
on Hyper Offensive teams that appreciate the offensive rock typing and its great resistances to Fire and especially fairy moves that allow it to switch in and stay in on some prominent meta threats. It's ability to wall break
, something many other offensive threats struggle with, gives it a nice niche in some scenarios on top of the aforementioned reasons.
