Honestly, you don't need to be an expert with IVs and EVs to win at the battle subway, although I can expand if you're really interested in becoming a serious battler. I'll start with Blissey, which is an amazing Pokemon. The first thing Blissey wants is a Healing Move, preferably Softboiled [which Blissey learns at Lv. 16, so you may need to find a move relearner for that]. Next, Blissey wants to have a status inflicting move, so it can constantly heal while your Opponent suffers. I reccomend you give it Toxic, found in TM06, which you can find on Route 17. Finally, you should always switch your Blissey when you see a Pokemon that uses Physical Attacks. It may be hard to deduce, but just use your gut. Would something like Aggron use its powerful bulk to attack you, or special moves? What about Alakazam? Knowing the difference between Physical and Special attackers is an essential step on the path of learning. By the way, your Blissey has a great nature.
Next up is Emolga. While a cute Pokemon with nice typing, Emolga is inferior to Zapdos and Thundurus. If you are interested in training either Zapdos or Thundurus, you can find moveset options for Zapdos
here and moveset options for Thundurus
here.
I suggest catching another Cinccino, because it's essentially useless without Technician. Once it does get Technician, however, give it moves that hit multiple times, as well as those with a base power under 60. Some moves that fill the above requirements that Cinccino learns are: Tail Slap, Bullet Seed, Rock Blast, Swift, Wake Up Slap. The first 3 of those moves will need to be taught by the move relearner, the other two are learned by its pre-evolution.
Togekiss is more useful with Serene Grace, as it can constantly cause the opponent to flinch, but that isn't to say it's not useful without Serene Grace. Firstly, I suggest you give it Air Slash over fly, since Togekiss is a Special Attacker [move relearner], Aura Sphere over Ancientpower, since Fighting is a better attacking type than Rock, Aura Sphere has more base power and it can't miss. Finally, I suggest you go with Roost [to heal] over Echoed Voice or Nasty Plot, to boost up your Special Attack.
Simipour isn't a Pokemon with much potential, but if you want to use it, that's fine by me. Firstly, it doesn't need 3 Water Moves, all it really needs for STAB is Scald. I suggest you keep Acrobatics and give it Ice Beam and Shadow Claw for mixed Coverage, then you should be good.
Finally, we have Serperior. Impish is a bad nature for Special Attackers, so we'll focus on turning it into a physical beast. Firstly, give it Coil. Coil rases Serperior's Attack, Accuracy and Speed, so that will prove useful to it. You could give it Return, which has a base 102 Power when your Pokemon has reached Max Happiness [I assume Serperior has, since it was your starter]. I'd give it Dragon Tail, too, which you should use whenever your opponent is using moves to boost stats, another action that is fundamental to master. Finally, you can give it Leaf Blade, for Powerful Physical STAB.
