This Melmetal set shares great sinergy with SD Bulu. First of all, grassy terrain gives Melmetal much needed passive recovery and also mitigates earthquakes, making it even harder to ko. Bulu also has good physical bulk and resists ground, electric, water, dark and fighting type attacks, making it a great offensive checks to threats like shifu, chomp, landot, koko and zeraora. Conversely, melmetal takes on STAB attacks from monsters like lele and Kyurem while having enough physical bulk for Weavile.
The main sinergy between the two, however, is how melmetal helps bulu break teams apart. With thunder wave it cripples many shared checks like Pex, corvi, skarm and volcarona, while also being generally useful for a slower breaker like tapu bulu. Thunder punch makes for consistent damage against those threats. Consistent and free from all the rocky helmet/flame body bs thanks to the gorgeous item that is protective pads.
Ice punch as an alternative to superpower because bulu already has close combat and most of all to murk garchomps and landot that could prevent you spamming twave and generally annoy melmetal
Speed is for Pex, but you may want to invest enough to outspeed hippowdon
tl;dr these two are strong attackers with great defensive utility and offensive sinergy
