Which Regi is best for this setup?

My friend wants to use a regi- ce / steel / rock on his team. It will hold assault vest and be awesome in defense. Their individual movesets, EVs, nature, etc don’t matter right now. They will get a baton pass from…

Whichever regi has the best defenses your opinion after calculations ((2.2 x (Base Stat x 1.5) + 108) x 4) should be your answer. That formula includes 3 ID and / or Amnesia boosts and assault vest, converted all to an actual stat.

I’m sorry to burst the bubble, butthis will NOT work as wanted.Why?

Those 3 are weak to Fighting-type, one of the most common types. In addition, 2 of them are weak to Ground ; 2 are weak to Fire, and 2 are weak to Steel. If the plan was to use them altogether, then there would be no synergy at all. But even then, none of the 3 would synergize with the rest of the team. They also have pathetic offensive stats and Assault Vest prevents them to boost except through Power-Up Punch. Even then, as replays demonstrate, the attack should be supereffective to do anything significant. So the strategy is a big no actually, sorry.

If your friend is adamant on using this strategy albeit pretty bad, thenRegisteelis his best bet.

TL;DR: the very nature of this strategy is pretty gimmicky and will not work.

From what I understand, you’re asking what Regi should be used.

And I think the best one for that is Regirock.It has naturally high Defense that can be rounded out with an Assault Vest, and with Power-Up Punch and Drain Punch, it can boost itself and keep itself alive. Here’s the set I would run:

Regirock @ Assault VestAbility: Clear BodyCareful NatureEVs: 252 HP / 252 SpD / 4 Atk-Power-Up Punch-Drain Punch-Stone Edge-Earthquake

Based on that formula, you should run Registeel as it has the highest base SpD compared to Regice and Regirock. You could, however, run regirock as the assault vest and stat boosts would raise his SpD to balance with his base 200 defense.
