So you’re trying to come up with six Pokémon for your team in order to pummel friends and conquer the online scene? Then one important thing to think about are the types of the Pokémon you’re putting in your team.
A Pokémon with little reason to consider would be Ducklett, for example, its dual type of Flying and Water makes him incredibly weak to Electric attacks, and while the Flying type cancels out the weakness to grass, it’s now weak to rock which is normally an easy strength for Water types.
A good Pokémon to consider would be Galvantula. A Bug & Electric Type its only weakness’ are Fire and Rock and while many players may try and use a Flying Pokémon against it; its Electricity cancels out this weakness. Also being a bug, Galvantula can learn maneuvers for taking down pesky Dragon Types, which is also helpful.
So consider Hybrid types, as they can sometimes throw opponents off and lend themselves to sneaky tactics, but try and avoid hybrids with shared weakness’ as they can be hit extremely hard.
Quite a bit wrong here; there a loads of pokemon that have 4x weaknesses, but have many redeeming factors. Weaville, Tyranitar, Scyzor, Heracross, Leavanny...
It doesn't take into account Pokemon abilities either - Electross, an electric Pokemon. It'd be weak to ground moves... Nope, it has Levitate.
As a rule of thumb an Increased Stat will add 10% to that statistic while a Decreased Stat will cause a 10% decrease. Nature’s are handed out at random when you catch or hatch a Pokémon, and getting your perfect Nature will forever annoy you.
Catch a load of Pokemon with the Synchronise ability and there's a 50% chance of meeting a Pokemon with the same nature. When breeding give the mother an everstone and it's more likely to pass on the nature too.
IVs
IV stands for ‘Individual Value’, which, unlike EVs, cannot be affected through training and, unlike Natures, are extremely difficult to work out. Put simply, some humans are naturally better at some things than others, your friend might be stronger through no effort on their part while you are stronger, and every Pokémon you encounter in the game has its own Individual Statistic that is personal only to that individual creature.
There's a guy in the subway that rates your Pokemons IVs.
You can also use Feathers found on Bridges and drugs such as Iron and Zinc to add up to 100 Evs to one stat, meaning you only actually have to train the remaining 155 points.
The feathers only increase it by 1, the medicines increase it by 4 (1 whole stat). You can only use 10 medicines, but you can use as many feathers as you want.
