Alright, goodbye, NDAG. And hello, NDUBERS!
We commonly see Kyogre bulky, with a scarf or specs; all are deadly in their own right, but all of them face one issue: Primal-Groudon eats their attacks for breakfast, lunch, and dinner. Its mere presence makes spamming its STAB a high-risk low-reward, not to mention that it gives Primal-Groudon a free turn to do whatever it wants if it does so, or its teammates if it decides to go big-brain! And trust me, the last thing you want is to face a +2 Primal Groudon, or a +3 Zacian-C if you lock yourself into Ice Beam.
This begs the question: what if we can flip this seemingly frivolous, one-sided matchup 180 degrees and punish them for this while being consistent against other archetypes simultaneously? Gone are the days of running! Behold, Z-MUD SLAP!

If we're going to do this, we might as well go all-out! The former avoids the OHKO from +1 Jolly & Adamant Zacian-C's Wild Charge from full while only having a meager 18.8% chance to be OHKO'ed by the Jolly variant after Stealth Rock. 20 Spe outspeeds everything up to paralyzed Pheromosa.
The latter, on the other hand, avoids the OHKO from 252+ Primal-Groudon's mighty Precipice Blades from full after Stealth Rock. 88 Spe creeps nothing in particular, although it helps vs. various Primal-Groudon with obscure speed EVs. You can tinker with it however you like.

Pair this with threats that hate Primal-Groudon like Zekrom, Zacian-C, Arceus, you name it!
Take our raging fury buried within the tectonics, you ruler of the precipice!
