You're suggestin' a VGC Doubles set for a Singles team lol. Gems are in no way optimal items in Singles and should really only be used to KO specific hard counters ubiquitous in the metagame that one should expect t' see... which is irrelevant to this team since Lucktown isn't some superMLGprolegit competitive player (... yet? ) and isn't gonna be usin' some complex EV spread designed t' Speed tie or outrun all opposing Jolteon and OHKO with Ghost Gem-boosted Shadow Ball... or somethin' crazy like that. T'is an important thing t' consider when givin' team suggestions. I ain't sayin' to not give suggestions, I'm moreso sayin' to consider if your suggestions are a good match to the player. A good VGC suggestion can be a terrible Singless suggestion and vice versa.
Ampharos does suck though.
We've already had this dumb discussion 'bout Ubers. ._. It's an entirely valid tier of competitive play, and anyone who thinks otherwise doesn't realize how far they've shoved their head up their arse. Few would think that 'less they've either not played it or never gave it enough of a chance. That's tantamount to embracing a retarded ideology similar to that one popular amongst casual noobs: that all legendaries are OP. The opinion Ubers is shit is clearly an unfounded opinion on your part since if you lack Singles experience, it's quite obvious you're particularly inexperienced in Ubers and therefore have no merit t' speak on the subject.
Furthermore, you do realize VGC once had Ubers a part of the metagame, no? This makes the statement "Ubers is for noobs" hypocritical in light of this fact alone. 'Specially when you're not supporting this (utterly incorrect) sentiment with actual facts. You've foolishly bashed on Singles and now you're thinkin' low of a specific tier without any discernible reason.
tl;dr: Educate yourself instead of presuming. Ya can validly (but still incorrectly) say Ubers is n00bish once you have plenty of experience in both Singles and Doubles Ubers. That goes for any other tier or ruleset as well, so no, I won't accept "VGC (year) sucks BECAUSE of Ubers" as a retort 'less you've extensive experience with that ruleset.
... With that said, please forgive me for that spiel bein' so blunt and direct. I couldn't really figure out a way t' properly present my opinion without bein' confrontational. Possibly 'cause I typed this up just after wakin' up... before breakfast. herpderp. My following response shouldn't be anywhere near as heated. So yeah, sorry if it appears I'm speakin' rude-like and such, as that's not my intent. It's moreso a symptom of my adamance on the matter.
