I need help deciding between two special walls for my RU team. One has more HP but less Special Defense, while the other has less HP yet more Special Defense and Defense.
Meganium @ Leftovers
Nature: Calm
Ability: Leaf Guard
EVs: 252 HP/4 Def/252 SpD
-Leech Seed
-Hidden Power {Rock}
-Aromatherapy
-Giga Drain
Meganium has base 80 HP and base 100 defenses, making it appear to be the better choice, however, having Aromatherapy but no Wish makes Meganium's movepool a weaker asset to the team, although Leech Seed assists in teammate recovery and wearing down bulky, non-grass-type opponents. Giga Drain for recovery and Hidden Power {Rock} to assist in my Bug weakness that also affects another teammate.
Clefable @ Leftovers
Nature: Calm
Ability: Magic Guard
EVs: 252 HP/4 Def/252 SpD
-Heal Bell
-Wish
-Seismic Toss
-Protect
Clefable has base 95 HP, 90 SpD, yet only 73 Defense, which makes for a better special wall, but for a weaker one overall, which will also guarantee that almost any fighting-type Pokemon can knock her out in one hit. The movepool more than makes up for it, though, as an incoming teammate could be gaining 197-101 HP on the switch in (depending on whether I'm doing level 50 or 100 battling). Protect can scout, and also ensure the healing from Heal Bell, rendering Softboiled a waste of a moveslot which allows for Seismic Toss for a steady 50-100 damage when needed.
Which do you guys think will better fill in the role as both a special wall and supply team support?
