Okay, so you've heard about the Reborn League and want to take it on with your very own team. Here's yer helpful advice.
One thing you should know about the League is NOT EVERY BATTLE IS A SINGLES BATTLE. Meaning, you could possibiliy face a doubes or triples match. Hardy is a great example.
Moveset
While Making your team, you have to decide which move is actually worth having and which move would backfire. Examples of this scenarios are Earthquake and Uproar. Earthquake can do massive damage to two enemies at once, at the same time; doing damage to your alley. But, with the right abilites and right typings, this threat can be avoided. We'll come to that later. Uproar is a unique move that does damage to a random Pokemon on the field. With luck, it could do massive damage, but in the world of competitive battling, you can't afford to have Luck. Moves like these are not to be even considered, unless you happen to be extremely lucky. Some moves do not rely on the speed of the Pokemon itself, but it's PRIORITY instead. These moves allow the user to go in a fixed order depending on the priority points instead. A +1 Priority move would allow the user to move first, as shown in +1. A -6 priority move would force the user to go last. Some moves depends on the status of the target (Dream Eater, Hex). Some move causes additional effects. Moves like this can either cripple the target (Scald with 30% Burn effect) or boost your stats (Flame Charge with +1 speed) <more on="" stats="" soon.=""> Some moves do not even do direct damage. Some examples are Poison Gas (Poison effect) and the Recover (Heals 50% of your total Health Points). These moves either boost your Pokemon/Entire Team, or cripple the target/Target's team. A famous cripple combo would be the Spike (When switched in, does Damage to Pokemon that do not have the Levitate Ability, or the Flying Type)+ Poison Spike (When switched in Poisons/Badly Poisons Pokemon that do not have the Levitate Ability, or the Flying and Steel Type) and the Stealth Rocks (Does Damage to Pokemon when switched in). There fore, it is important to first determine if your Pokemon is based on firepower/Cripple/Booster.)
Abilities and Types
This is an interesting section. Pokemons are gifted with many types of Abilities and different types. This itself is an advantage and disadvantage at the same time. Some Pokemon are able to have two different types at once, examples are the notable Bulbasaur (Grass/Poison). With different types come different results. Some types are effective against each other (It's super effective!), while some types do not do effective results with one another (It's not very effective...) This enhances my points of disadvantages and advantages. You should be able to find a list of comparability with each type. The effectiveness of a move depends heavily on the target's type. For example, Toxic does not work on steel types. This makes Toxic completely unusable and thus rendering the user with only 3 moves. (More on Update)
Stats
Stats are the main power-points of a Pokemon. With a high Attack/Special Attack stat comes highly offensive attacks while high HP/Defense/ Special Defense help the Pokemon take hits without bulging. High speed means... High speed? Of course, it would be great if a Pokemon had all of the stats at its highest point, but, Pokemon like these are called Legendary for a reason.

That's all I'll be typing, cause currently I'm unable to use my computer and my phone's not the best typing material. I'll update this when possible. Meanwhile... Tips? c:</more>
