After playing one Nuzlocke runthrough of Black that involved me soft-resetting approximately 30 times cause I'm a wuss, I decided to MAN up and restart the game, this time being a MAN and not chickening out no matter what.
Currently I just entered Victory Road, about to face the E4, and only one Pokemon in my entire journey has died so far: a fodderish Lillipup I had to sacrifice to a Timburr that was about to kick my ass with Bide (why does EVERYTHING at the start of the game know that move?!). Well, technically my Stoutland died while I was capturing Cobalion, but I gave that a pass since I deemed legendary catching not part of the challenge per se. So, my (hideously overlevelled) team so far, and a few thoughts to go with them:
Lin the Samurott
When I first saw Samurott's stats long before I'd bought the game, my first thought was: meh. Very meh. Then I grabbed meself a Wotter and watched it mutilate and pulverise all that opposed it with its pair of cute little seashell-blades. Seriously - this thing is so good for Nuzlocking, it's not even funny. Hits harder than you'd expect, moves faster than you'd expect, and takes hits a whole lot better than you'd expect (I've rarely seen any move, even a SE one, do more than 20% damage). This little otter kicks Tepig's butt any day.
Summer the Stoutland
I think the key reason my runthrough was so much easier this time was because I managed to grab a Lillipup off Route 1. Not much to say, other than that Intimidate is the best f***ing ability ever, and STAB-boosted Return is so rediculously overpowered with an Atk-boosting nature that it simply defies description. Essentially she takes hits from both ends of the spectrum like a champ, and returns them with unholy amounts of power. GREATLY helped me through the early game, and still a fantastic battler now.
Dahlia the Excadrill
Okay, er, let me explain a bit. Dahlia WAS technically the first Pokemon I saw in Wellspring Cave. To ensure that, though, I did use three Repels in a row and do a hell lotta running until I saw that lil' dust cloud pop up. Okay, so maybe that was kind of a cop out, but getting a Pokemon that can basically OHKO the entire Dragon gym (and, as an afterthough, around 95% of the game) certainly helped clear my conscience a tad.
Nikolas the Chandelure
I'd been looking forward to rearing one of these things since I started the game, and what can I say? I'm sorta disappointed. Don't get me wrong - this guy OHKOs literally everything I've thrown him against, and I mean everything. The problem is he's a tad on the slow side, and also doesn't brush off attacks all that well on the switch-in. That, and he joined the party a good 17 levels after my most recent addition, Dahlia, did, so maybe the connection ain't quite there. Still, I'm sure he'll be a heck of a help in the E4, so I'm keeping him around for now.
Ruckus the Waruvial (I think the Jap name sounds so much cooler)
The only member of my team I hadn't planned on getting from the very beginning (yeah, that's how I play, deal with it :P). Basically just felt I wanted a fifth to round out the team, so I was a choice between this dude and Chick the Gurdurr, cause they were both Adamant (YEAHHHHHH). Ultimately went for the STAB-boosted Crunch, and convenience during evolution, since I'm the just about only person in my school who bought the game on DS instead of downloading it onto their laptop. Suffers from many of the same problems as Nikolas, and similarly hoping he'll redeem himself in the E4.
Sorry for the long-winded post; I'll probably update later to tell of how the fight with Ghetsis went. Final comments: the Eviolite saves lives, ALWAYS have the Lucky Egg attached to something, and for gods sake remember to grind like a motherf***er, or thou shalt perish.
