Haha, dude no problem, because in all honesty, it seemed to have required a fair amount of thought and testing; I saw you had done that.
And the sprites are your choice xD I just think Tyranitar looks retarded (and he's my 2nd fave pokemon tied with Heracross), but Metagross basically is 4 pillars w/ spikes and a brainy-shaped head in the middle of them all, so that one's accurate. But, DPP's Tyranitar sprite makes Tyranitar look fierce while HGSS's Tyranitar sprite makes him look like a demented giraffe that's happens to be green with a purple tummy.
lol, rant.
