No way. This is brilliant and nowhere close to cheating.
It makes Zoroark the perfect lead! Wait, no, I take that back. He'd be the perfect lead if he could learn a field effect move (Spikes, Stealth Rock, etc.).
Seriously, the first move in a match is one of THE most important to set up your flow for the duration of the battle.
If your first choice is wrong (and it most likely would always be against Zoroark) you'll lose a significant advantage.

That being said, you'll only lose the first-turn advantage.
Not to mention, most of what players do in the first turn is try to out-predict, usually ending up in a switch if they feel they're about to get shafted.
IF Zoroark's illusion Does force a switch, it's probably not going to be overly advantageous to Zoroark's trainer, because Dark isn't an exceptional type. (Sorry, Dark-lovers.)

Bottom line: he'll be a good choice for a lead, maybe a "panic button" later in the game. But like Frost said, his ruse will only last one turn.

I really don't think of it this way. It's more strategy and anyway, after a few supereffective dark moves it could seem pretty obvious that, iunno, for example, a alakazam using all dark-type moves.
But as frost said, it will be a one-turn advantage but maybe that's all you need? I do hope that zoroak isn't a one-trick pony though and has other good points about it other than it's ability.

Judging from the fact that it has a move which boosts Attack and Accuracy, my guess is it'll be pretty flippin good.

I just hope that it's ability is used on it before the opponent even gets a look at it cause if not then everything fall to **** ...I mean come on, I bet it will be released from the pokeball & then Illusion will kick in right in front of the opponent's eyes which would make this ability utter crap imo, I hope it uses Illusion before it is even released from it's pokeball cause if not then it's a no-go, all bark & no bite...

As far as the attack is concern, it is centuries better then Illusion no matter how you look at it meaning I actually like the attack...

Probably the source forgot to mention it, not you so yes but no...Good, this ability is at least a little bite now, I can accept it as a usable ability now, whew that was close...

Well see, that's the message I got from the page on the event that explained how to get it ingame available via pokemon's japanese site so...

EDIT : Oh, nevermind, it's regular Entei & it shows Entei transforming back to Zoroark...hah...

i was thinking that, but wasn't sure; the only thing i knew about the transforming back was that during the event w/the legendary dogs, it sometimes transforms back and that's when you can catch it. i wasn't sure if there was a way for it to turn back during a battle against trainers (tho it's kinda common sense that it would, looking back on that thought)

this means we're probably gonna start seeing gimmick-teams ({smeargle}{ditto} and zoroark filled, i'll bet) that pretty much just showcase illusion. wonder what other interesting stuff they have tucked away....

I'm thinking Zoroark's ability is just like a free substitute. Like, if he could learn Nasty Plot, have a Houndoom or something second in line, and just use nasty plot like 2 or 3 times then Baton Pass or something. I don't know.

According to Bulbapedia, 4 new pokemon have been revealed, but they are not confirmed to be legit. t2 of them look like the second evolutions for the grass and water starters. See here http://bulbanews.bulbagarden.net/wiki/File:BW_anime.png .

Aww man, does this looks fake too! But maybe this time it actually might not be but getting back to why I call fake on that, why show only 2 of the starters 1st stage evolutions & not all 3 of them?...this being said I can't wait til the 5th Gen portion of the anime premieres so I can identify the trainers ages...

Everyone the actual pictures ov the three starters are on lolstop at the very top of the page
left to right:
left: grass
middle: fire
right: water

I am guessing that it will come out in the US between March & May of 2011 & for the UK date, I don't know...same as the last games?...

Probably, I don't know...I just though that maybe this time they will stay on a fixed schedule which some people have done in the past with other game projects...

I was getting the White Verison up until I saw that my more favored Reshiram was in fact in the Black Version so now I am getting the Black Version unless I hear that you can get both of them in either game at different or the same point in your adventure or if the exclusives(which I care about more) for White is better then the exclusives for Black...

I don't see why there wouldn't be a 3rd game...I just like to have every version in my collection so that I don't have to relay on other people just to complete something but then, even with all the games, sometimes you still end up doing this which is quite depressing...
