When you are about to enter Altrua Tower
The capture styler has 99 levels.
You must get to the end of the game to get the last styler, the vatonage styler.
you can in Japanese shops
The fourth styler is only gotten at the last part of the game and is the Vattonage Styler.
My way to do it (pokemon ranger) is after he attacks poke the fires out (it will make you loose styler energy) and then capture charizard
japanese amazon and yahoo auctions but they only ship to japan
Its capture is the same as other Pokemon, but i recomend you to get magnemites or any other Pokemon that can recharge your styler, it is a hard one.
The fourth styler's position will vary depending on the order you choose to recover the school stylers. Firstly, one styler can be found in the faculty/staff room. Capture the Pichu in orer to obtain the styler it is holding. Two crates in the library require the crush Field Move of a Bidoof. Destroy these crates in order to obtain the next styler. Your classroom now has four crates inside. Use Bidoof's Field Move on the crate to the right of the teacher's desk. Inside you will find the next styler. The classroom next door (to the right) will contain the last styler. It is resting on a desk towards the back of the room. Go over and collect it, and you will have all four stylers.
try to use a Pokemon like medicham to make your styler do double points on poke assist
If you mean in the ranger school here is how. You are going to have to use the bidoofs that are in the hallways. A few of them. One stylus is in the teacher's lounge and you have to capture that minun or plusle(I forgot what one it was) and it has one of them. You get it from it by befriending it. The next one is in the library. There will be a lot of boxes, the stylus is in one of them. You have to have atleast 2 bidoofs or more for this one. Use a target clear on each box until u find it. Next is in your classroom next is Mr.Kincaid's room. I will only tell you that. Have fun! Hint: once you put them downstairs, you have to befriend gastlies.
Capture a Pokémon that gives lots of Exp., release it, leave the area and come back, repeat.
if you mean school styler, styler you get at vientown base , fine styler and vatonage styler, you get them by completing missions
