Cacturne breaking down teams
Battle 1
Battle 2
I didn't even play Cacturne as well as I could have in these battles, fyi.
There's still something to be said about a powerful mixed attacker with dual STABs that score huge damage on a large majority of walls in NU and has access to the single most raw damaging priority in the tier (even stronger than Fletch's Acrobatics), not to mention that while its bulk is pretty ass Cacturne has more than made up for that with its useful resistances. Need I mention Cacturne's Sucker Punch is more effective than it meets the eye, due to Cacturne's immunity to Sleep Powder and Aqua Jet?
That's just talking about the mixed attacker set; I have not even discussed the Swords Dance variants and Spiking variants. Swords Dance Cacturne could give a rat's ass about Unaware Quag, and its boosted Sucker Punches will brutalize just about anything that isn't resistant or carrying priority of its own, this is still reason enough to run Wisp on your LO Pyroars even with Yama's slight decline. As for Spiking Cacturne, well it's essentially a variant of the mixed attacker set (I just have Spiky Shield on mine) that uses its resistances and offensive presence to set up on walls; if you've seen in those battles I could have plenty of opportunities to lay down some Spikes despite Cacturne's awful bulk. The appeal to Spiking Cacturne is that it can maim nearly every hazard remover in the tier, with the sole exceptions of Togetic, Mantine, and Pelipper (the latter two need Flying attacks to properly retaliate), and even Xatu would hesitate on switching into mixed Cacturne.
I will admit that Cacturne is probably one of the more deceptive A- Ranks we have, but further testing has definitely convinced me of its niche. It's not like Cacturne has gotten much worse in this meta either: while new faces such as Fletchinder are not a pretty sight, targets such as Lanturn, Stunfisk, and Gourgeist have risen in prominence for it to take advantage of. Cacturne is fine in
A- Rank.
Edit:
marilli Spiky Shield also has the benefit of letting me scout Choice users (Sawk), scout for coverage moves (does Yama have EQ to hit my Garbo switch?), and even punish priority users like Swellow and Zangoose, especially with their dwindling health. Of course, Spiky Shield is not something I'd recommend just throwing onto Cacturne; it just so happens I happen to have decent defensive synergy among my team and have Toxic Spikes going, making the stalling + chip damage a more significant factor.
