Just to let you know, Hariyama WOULD have countered Typhlosion.
Turn 1:Typhlosion uses Eruption as Hariyama switches in. The Berry activates, and Typhlosion is droped to 88% hp = 261 hp. Hariyama at max takes 228 damage, which leaves him with 236 hp.
Turn 2:Typhlosion uses Erutpion. Due to the droped hp, Erutpion now has a base power of 131. Hariyama takes at most 198 damage, which leaves him at 38 hp. Hariyama retaliates with Earthquake, which more than half the time is an instant kill, but we will say it did minimum damage, 253, leaving Typhlosion at 8 hp. Eruption now has a base power of 4. Blaze activates.
Turn 3:Typhlosion uses it's 4 base power Eruption, doing .... 12 damage max to Hariyama. Hariyama uses Earthquake. Typhlosion dies.
This is assuming each time, Typlosion did the max damage that Eruption can do. But because of the berry, Hariyama is saved!

Hidden Power Ground is a 3 hit kill assuming all 3 hits do max damage. But if they did, then it would be fair to grant Hariyama atleast average damage on his one Earthquake, which would be all he needed to kill Typhlosion if he used Hidden Power.

Unevied, it can take even the Petaya Berry Boosted Frenzy Plant and Focus Blast with no problem. And uneved, SludgeBomb is an instant kill. Being a Grass-Type makes it immune to Leech Seed as well. You can only Substitute for so long before you die. EnergyBall is a very nice Stab, Shadow Ball and Hidden Power Fire are type coverage.
Roserade isn't going to last long though... although I can't truly predict who's gonna counter it, since you guys are starting to step up your games. I'm expecting Super-Effective damage though... probably something that doesn't take super effective damage and can strike back physically. That's my best guess. The only Pokemon that takes reduced damage from this set is Heatran. And most special walls in UU will typically be outspeed, and will require much power into their defenses and hp in order to have a chance of surviving the 2 hits, which means it might be hard to have enough power to insure an instant kill (Lanturn, 3 Energyballs have your name ALL OVER THEM, and it would take you a Calm nature with maxed out Special Defense and Hp to live through 2 of them, while your Ice-Beam would be lucky to get a 3 hit kill!).
It's either going to be a counter with Item involvement or a very obscure plan, again most likely using a Physical move.
