My thoughts on this thread:
First off, I think this is a great idea. 40 posts/41 views means this is a popular thread too, just about everyone is giving their opinion, and with enough popularity, who knows it might just reach the right person and Nintendo may put the Smogon created Pokemon in the next game. It's definitely worth trying, and even if it doesn't go through, its still fun to see where this thread goes and what result we get at the end of it ;D
As for the typings:
Steel/Bug has been done. Three times. I don't think it will be either as good as Forry/Scizor, or much different either. Plus, on a less important note, if Nintendo DO pick up on this idea, they probably aren't going to want a Pokemon thats already been done.
Ice/Steel: I like the fact that steel covers Ice's Rock weakness. But with the 4x Fire/Fighting weaknesses it brings as well as new ground weakness (all extremely common types), it makes the options for this Pokemon very restrictive if we want it to be OU. For one, it can't be defensive. And if it has to be offensive, a Steel STAB means it has to be physical to be decent, Meteor Mash is the only good steel attacking move, bar Gyro Ball, but this guy will need his speed with those weaknesses, so you can rule that out. Flash Cannon would maybe allow you to go special, but really I'm just seeing a worse version of Magnezone here due to the fact that it's defense is teh suck.
Ice/Bug: I've already said alot about this typing. But basically, everyone is worried about the 4x SR with this guy. Magic Guard isn't actually needed, a Rapid Spinner can do the job fine. Although Magic Guard would be an alright ability on it and wouldn't be broken either on an offensive Poke. Once the field is clear and this guy switches in immediately, not much Pokez can take STAB Ice Punch or Megahorn, with (hopefully) EQ and Thunderpunch to support it. At least thats where I'd like to see this Poke go. Specially orientated makes it too similiar to Yanmega.
