Silvally-Fire has very little standing in its way thanks to the general lack of Fire-resists in the NU meta. That makes its coverage as an SD breaker more or less situational, as a boosted Multi Attack is so strong. To bolster that strength, I made a Sun team centered around it. After an SD in the Sun, Silvally 1HKOs Piloswine and Sandaconda, two Ground-types that teams often rely on their bulk to revenge kill. Water-types like Wishiwashi and Lanturn also do not threaten as much in the Sun, so Silvally can setup and break through them with the right support. Dragon Claw is for Drampa and Dragonvally, and that support will help the Grass sweepers on the team spam their STAB moves easier.
Vulpix is needed for Drought, and is played very expendably. It usually is a lead, and relies on switching into Hattrem and Sandaconda. Memento, Encore, and maybe Toxic (haven't clicked it much) means that not much can capitalize on it. Leafeon is a killer sweeper that is still max Speed so that after Sun it can still clean teams in a similar vein as Silvally, and shout outs to
Rabia for catching that I should run Solar Blade over Leaf Blade lol. Ivysaur is even more dependent on Sun but its super strong Fire/Grass coverage is perfectly complemented and tears through the tier; seriously, most teams do not have resistances to this coverage as they often lack Fire-types themselves. Sleep Powder can help with setting up Growth, as well as help get Vulpix in if Sun runs out. It is very bulky and can setup on the likes of Garbodor and Cofag, and can stil outspeed Frosslass. Sanda helps as always with Glare and SR, and enjoys not being so weak to Water. Hattrem is a much needed hazard control mon that checks Grounds like Quag too with a spread that gets the most HP outa Giga Drain while still being physically bulky.
