How would you go about remaking Ruby/Sapphire/Emerald

If you don't have a solution for something, it's going to severly cripple or outright beat your entire team every time you see it. Every team didn't have a solution Reuniclus, but those same teams were losing to it at team preview. CM Reuniclus in particular was one of those pokemon that would beat your entire team if you didn't carry something to prevent it from setting up and/or something to 1-2HKO it. Lacking a check, counter, wall, or revenge killer for any pokemon used frequently enough to be OU is bad team building

I don't understand how you come to this conclusion. Look at mega kanga, it's ability made it so a fake out+ any neutral move would 1hko a monster. I'm not sure if you know how they define tiers and [MENTION=846]Corn[/MENTION]; can correct me, but it's based on essentially how it, percent wise, affects the major combatents in the metagame. That's why in random matches on smogon theres level scaling so that you don' win simply have a rayquaza on your team.

In this case, politoad's ability with swift swimmers became banned because mon's became necessary to counter it, a monster with 40+ positives and less than 5 negatives is going to have whatever strategy taken away. Talonflame, which I'm sure is on your mind as an example in this discussion, has plenty of counters, where it still adds team variety and balances him within the tier.

Weather teams meta was the worst meta I have ever experienced. There isn't a single counter that can affect a weather team, that a weather team hasn't already saved a slot to counter-counter. You're essentially trying to blame the ban/nerf on unexperienced players, when people who could play circles around you, notice, plural, decided on this because the game was considerably skewed. In fact so much so that the frekin company changed it.

Excadrill is one of the best rapid spinners in the game, if not the best. Mold Breaker is its most common ability by far, likely because of Rotom-W and extremely short duration of sandstorm.

In current meta this is true, as is rotom-W pretty much the best defensive poke in the current mea, since physical attackers are so prominent which gives a major use to will o wisp.

TTar has been OU since GSC and gets buffed in ne way or another every generation, I doubt he'll ever fall from OU hehe. Among many other things, TTar is a Talonflame check, a SR setter, a powerful pursuit user, a ghost resist, and a special wall (especially with assault vest). Unlike last generation, though, his sandstream provides much less support for pokemon other than himself (SpDef boost). So much less that building a team around it is gimmicky, at best. The same can be said about Politoed, Ninetales, Abomasnow, and MegaCharizard Y and their respective weathers.

He's a pseudo legendary, Dragonite has gotten major buffs since 5th gen. The meta game is going to drastically change with the release of pokebank and move tutor. Focus blast will be much more common for example. I don't understand the rest of this, you point out why TTar is a usable pokemon, but say that a team around it is gimmicky? You mean for his sandstorm ability? Weather abilities have become essentiall a buff for burst damage. In fact we should see more fire teams since charizard Y/Ninetails are both auto weathers.

To be honest I'm not sure if you understand how the metagame works, everyone with half a brain know that Goodra was specifically made for politoad rain support.
