This is a take on an MDiancie Weavile team I've had for a long time, the main structure of the team prays on mixed balance/BO teams that have trouble dealing with Mdiancie after webs are up and especially when soft checks to mdiancie like corviknight and mega scizor are trapped by zone. Apart from being a fairly standard rilla zone with Z-Ice greedvile what sets this apart is the synergy between MDiancie and Rillaboom, while rilla+zone is often discussed Mdiancie isnt thrown into the combination as much, this mon actually forces out all the rilla checks that zone doesnt such as Buzzwole, Kartana, Volcarona and Zapdos and any Tangrowth pdef enough to check a SD Rillaboom.
This Heatran set is the most brutal stallbreaker ive ever used its a 6-0 machine vs fat , After a metal sound you are at +1 and they are at -2 Which is the equivalent of you being at +4, it is impossible to downplay how strong a +4 Heatran (mon with no counters at neutral anyways) hits. and even if they choose to switchout instead of taking the +4 hit most teams do not have two mons that can switch into a Heatran, especially not a +1 Heatran with webs up. This Tran can fight a full hp av gking with earthquake and win, easily 1v1 Chansey without having to carry taunt or toxic, tear through calm minders like Clef and ohko a full hp 244/244spdef Gliscor at +1.
