Chansey is a good one. It is one of the best mixed walls in the game because of the Eviolite, raising its defense by 1.5x the original amount. While it may seem strange with such low defense, its gargantuan HP stat makes up for it.
Here's the moveset I like to run:
Chansey @ Eviolite
Trait: Natural Cure
EVs: 252 Def / 252 SDef / 4 HP
Bold Nature
- Toxic / Thunder Wave
- Wish
- Seismic Toss / Heal Bell
- Protect / Softboiled
Toxic or Thunder Wave is your choice of status, slowly taking down the foe, or supporting sweepers and yourself with the ability to move first. Wish it to support sweepers and other walls with no reliable recovers, plus yourself. Next, Seismic Toss is ideal to deal some damage and not become Taunt bait, while you can still go for Heal Bell if your team needs the support. In the next slot, you can either run Protect to receive the Wishes for sure, or Softboiled if you just want to pass Wishes to your team mates.
The next one should be used in NU/RU, and only there. Miltank is a great choice for a physically defensive wall in NU/RU due to its nice support movepool + high speed and decent defenses.
This is the ideal support set:
Miltank @ Leftovers
Trait: Thick Fat
EVs: 252 Def / 252 HP / 4 SDef
Impish Nature
- Heal Bell
- Milk Drink
- Seismic Toss / Body Slam
- Stealth Rock / Toxic / Thunder Wave
Heal Bell supports the rest of the team ridding of harmful status. Milk Drink is Miltank's reliable recovery to keep it alive longer and support the team. Seismic Toss or Body Slam are your choice of an attack, Seismic Toss has set damage and can hit steels and rocks better, while Body Slam comes off a very usable attack stat and has a chance of paralysis. The next slot is a toss up between Stealth Rock, which supports your sweepers, or 2 status moves, Toxic and Thunder Wave.
