@MoosePlus yeah, Amoonguss+Slowking can be annoying to break down if you're not prepared, but like any defensive/bulky offensive core there are many ways to beat it, i'll list three good ones below!
1) Sigilyph Sigilyph is a massive pain for Amoonguss+Slowking to handle once Sleep Clause is in effect (its actually somewhat problematic for defensive cores in general. Magic Guard means Sigilyph is immune to any form of passive damage, and while its bulk isn't stellar it can take almost any hit from either Pokemon bar something like Choice Specs Slowking Surf. Meanwhile Sigilyph can just Calm Mind up to the point where its strong enough to OHKO Amoonguss easily and 2HKO Slowking. Albiet rare, Duosion is quite similar if you give it 4 Speed EVs to ensure it outspeeds both Slowking and Amoonguss, and can be a great alternative if you can't accord to have any more weaknesses to moves such as Stone Edge and Volt Switch.
2) Substitute+Calm Mind Uxie Uxie is in a similar boat to Sigilyph, switching in on pretty much anything the two can throw at it bar Spore or a random scald burn, and from there it can set up a Substitute that neither can immediately break and set up Calm Minds until both Pokemon can be reliably KO'd. Take into account that Uxie isn't immune to residual damage though, so you have to be a bit more careful when attempting to switch it in.
3) CB Druddigon and Escavalier Druddigon is an absolute monster, and CB varients are able to pressure Slowking+Amoonguss quite a bit. Choice Band Outrage is incredibly powerful, and neither Pokemon can avoid being 2HKO'd at best by the dragon, often simply getting OHKO'd. Druddigon doesn't have a hard time switching in either due to its good bulk and resistances to Water and Grass-type moves. CB Escavalier is able to switch in and break down the core quite easily if it has 84 Speed EVs, it can outspeed and OHKO both Pokemon pretty easily with the extra investment and only fears Slowking's Fire Blast.
Of course there are some other ways to beat up the core, both common and more obscure, so if you'd like a few more be sure to reply! Hope i helped :).
