One of the recurring themes of the April Fools Giratina-O test and its aftermath was "why not Aegislash?" After all, Aegislash is kind of a chibi version of Giratina-O in many ways, though it doesn't work with numbers quite as ridiculous, and if Giratina-O is less broken than previously thought, then what about Aegislash? Well, we're about to find out. The best part is that there's virtually no consensus, so it really could go either way. The main complaint that keeps coming back is, believe it or not, that the OU tier is TOO VARIED, and thus it's impossible to cover everything with just six Pokémon, making many battles won or lost before a single turn is played. Aegislash would be a fix to that, because how long is the list of Pokémon that are totally Aegislash's bitch? Have you even SEEN the amount of previously unusable stuff that became good once Aegislash was gone? Yes, we're now at a point where a Pokémon could be unbanned BECAUSE it's overcentralizing. Goddammit, Smogon, can you just figure out what you want already? Then there's the outstanding matter of Aegislash featuring unparalleled synergy with Landorus-I, probably the most dangerous Pokémon at the moment.
Yeah, usually I try to recognize both sides' arguments because there are people much better and more knowledgeable than I am defending them, but I imagine you all figured out I clearly have all my chips in one pile this time around.
