Rises

C -> B
It has an incredible wellspring matchup and is a genuinely good wall and utility with spikes.

C -> B imagine if zapdos resisted knock off & the ever spammable ghost type? that's Mandibuzz

B -> B+ with decent speed, rough skin to punish contact, and hazards it can have great utility while still being threatening offensively

B -> B+ should've never dropped. great spinblocker, walls wellspring, overall great bulk and strength sap make it wall
any physical attacker.

B+ -> A
- completely walls wellspring unless it has play rough, and even than you could tera. which brings me to point number 2
- The only thing keeping it from ubers is a horrendous typing (unless it, idk, made u quad resist the most terrifying wall-breaker, lol could never happen) but it can tera. tera ground earth power against non steel types, steel to resist the previous crucial quad ice weakness and fairy weakness, and fairy for general goodness.
- it can both be a defensive pivot with regenerator, healing and incredible wellspring matchup, or a great nasty plot sweeper with the crucial ability to stay alive thanks to regenerator and use the many turns it has to cheese with fickle beam 30% double bp chance.

&

A -> A+ I feel like I don't need to explain myself.

A -> A+ With good bulk, healing with pain split, incredible hazard control that can be paired with a secondary rapid spinner against Hamurott to make you practically immune to hazards. psychic noise let's you disable stall with a single move on one pokemon, and it's versatility is great for itself as it makes it unpredictable.

A -> A+
Drops

wasting tera on a purely defensive mon sucks and the only thing that sucks more is being a rock type defensive pokemon. there's a reason it only has like ~7% usage.

when's the last time this not fast enough sweeper was seen sweeping? exactly. perfect covarage of off 135 sp.atk seems broken until you aren't fast enough for your paper thin bulk, don't have an ability to help you as a special attacker. and don't have anything to do other than moonblast & earthpower?

A- -> B+
A defensive pokemon that's weak to ivy cudgel? and can't cripple any incoming wellspring without giving up on 1 of your other important utility options? sorry buddy but this gen aint for ya kido.

A- -> B+ Why did it rise? it aint bulky enough for utility and is entirely outclassed in sweeping.

B+ -> B It was ou when sash

and

ware great, they aint meta now.
Bad typing & not incredible bulk while having less than 100 speed just sucks. & it isn't even that strong

completely outclassed by iron treads outside of sand and in sand too many pokemon wall it (Corviknight, Moltres, Zapdos, wellspring, air balloon Gholdengo & Heatran (most times drill doesn't have coverage)
