Ending Reigns of the Ginis: Thudy + Lando Counters???

[Aether]

My favorite, an absolute wall for both thundy, landy, and heatran. Storm drain is a great wall to the ever popular politoed, milotic and suicune.

252 Atk Parental Bond Mega Kangaskhan Return vs. 180 HP / 108 Def Gastrodon: 289-342 (70.8 - 83.8%) -- guaranteed 2HKO

Gastro's bulk gives it good survivability, and storm drain gives potentially recovery if paired with surf. Can OHKO most VGC threats if running offence, however if against a more (unusual) defensive set [e.g max HP/SpD M-salamence, Shuca-Tran, Max HP/SpD shield aegi] it can still pick up the 2HKO. Its abysmal speed also gives it fantastic potential in trick room.
