>>17489638>Isn't it better to go with 252hp and spd on mandibuzz to give it better defensive coverage? or at least a split in def and spd?Mandibuzz is generally used as a physical wall due to its typing (and access to Foul Play), but its special defense is more than good enough to make it work as a special mixed wall. Just dump 248 points into HP (takes less damage from SR and other sources of residual damage than 252) and do whatever with the remaining EVs.
Smogon suggests 248 HP / 216 Def / 44 SDef/ +Def nature (safely counters Lando-I),
248 HP / 40 Def / 220 SDef/ +Def nature gives it perfectly even defenses,
or you could do something completely different, like a spread that counters mixed Aegislash or something.
>what is the best evs to invest in for a large gourgeist? I know hp and deff but should I invest a little more in speed to out speed other walls?252 HP/ 252 Def/ 4 x imo. You could invest 12 Spe EVs to outspeed Blissey or 20 to outspeed Trevenant (assuming no investment on either), but I don't really see why you'd want to do that.
