Hi, I kind of went and read through... most of the past couple rounds of discussion. (I'm kind of disappointed that Zoroark was chosen as I'm not a big fan but hey, maybe this'll change my mind)
I'm a big fan of momentum-based battling, and what really stands out about Zoroark to me is his ability to gain momentum. Yeah, I sort of agree with Katakiri that Zoroark can be a good Pokemon on his own, but the main trait about Zoroark is Illusion, and by extension, the way Illusion can net you opportunities to win momentum. The way I see it, if Illusion throws the opponent off and forces the opponent to make a mistake
even once, Zoroark has done his job. Zoroark is far and away a Pokemon that creates opportunities for you to break away the game.
But, as ginganinja said, those opportunities quickly vanish the longer the game lasts. It also forces you to keep the Pokemon that you plan to disguise Zoroark as in reserve -- meaning that until Zoroark gets its opportunity, you have effectively two near-useless Pokemon.
Consequently, the best strategy for a team based around Zoroark is one that focuses on getting
just one opportunity to break away with the game (whether that is killing a crucial Pokemon with Zoroark or forcing the opponent to leave himself open to another Pokemon by dealing with Zoroark) and maximizes that advantage to the point where it can win you the game.
If Zoroark's player can't afford a mistake when trying to use him, [hyper offense] has the best chance of putting the opponent in a similar bind, after which it's a question of who can withstand the pressure more effectively.
Pretty much this.
So yeah,
hyper offense is definitely the best playstyle here.
As for sun... Sun teams are extremely rigid in their synergy and makeup. They always need certain Pokemon to function (Ninetales - Spinner - Chloro - Volc - Anti-Rain) and it would give us far less freedom to actually make a team. That doesn't appeal to me; we need to keep all of our options open as we move forwards as Zoroark is a difficult Pokemon to build a team for.
So again,
nonweather edit: not
nonweather, rather
nonweather OR any weather other than sun +
hyper offense.
And I'm not really going to weigh on Protect vs. Substitute yet as that is going to come down to the type of team we make. If, as I suggested, we are going to make a team that only really needs one opportunity for Zoroark, then Substitute >>>> Protect for fully taking advantage of that opportunity.
(So I suppose I'm more for
substitute assuming I get my way with the playstyle being hyper offense.
Maybe Nasty Plot, but, as I said, I don't think the point is to sweep.)
Zoroark shouldn't be a hit-and-run Pokemon that swaps in and swaps out; it should be that Pokemon that completely pivots the game in the user's favor, or at least nets you that one advantage that ultimately wins the game.
