What Evs and nature for MegaKangaskhan?

Question

I want to make a party for shingle battle in the battle spot. That party is the most famous combination in Japan (Mega Kangaskhan, Landorus, Cresselia, Heatran, Breloom, Suicune).
However, there are three types of Mega Kangaskhan which used in these parties.
Which is the best Evs and Nature?

---

Type1.
Jolly Nature
EVs: 4 HP/252Atk/252Spe
Maximam Speed for opponent Mega Kangaskhan or Charizard etc.

---

Type2.
Adamant Nature
Evs: 180HP/212Atk/116Spe
Speed 135 because opponent Breloom is 134 at most. HP203 for survive after 4 times of opponent Cresselia's Rocky Helmet(Power-up Punch and Double Edge) + 1.5 time of recoil of Double-Edge as much as possible.

---

Type3.
Adamant Nature
Evs: 228HP/252Atk/28Spe
HP209 for surely survive after 4 times of Rocky Helmet(136)+ recoil of Double-Edge against Cresselia(71 because opponent has 227HP and Power-up Punch give 12 damage at least).

Answer 1

Type 1 is the best out of the three as he becomes a sweeper, combined with great Ability and natural bulk, he is a pain to take down. Plus, it's the EV spread used by the VGC 2014 Champions league. Also, if you're running a champion set, Fake Out, Return, Sucker Punch, Power-Up Punch and Drain Punch go great with the EVS.
