Hey, we've all been there as spies. You see a Pyro standing still, so you go up to back stab him/her then before your knife even raises, you burst into flames while the Pyro is... well, believing. He was taunting with the rainblower. You curse aloud and think, how'd that happen? Well, here's how to find out by doing it yourself! Now, remember the phrase: believe in magic, because you're gonna be doing that a lot in this guide of rainbows and flames. So, this was just an intro on it. Here it is:
Step 1. GET THE RAINBLOWER!
Step 2. Join any game, whether it be Beta or not.
Step 3. After it loads, walk out into the field as Pyro and believe (attack) as usual.
Step 4. At first, you might want to find a Sniper. They are the easiest to believe in (kill violently) when they are zoomed in.
Step 5. After finding a Sniper, walk behind him/her and taunt while holding the rainblower. This has the same effect as taunting with the manmelter or shotgun or reserve shooter, it just looks prettier.
Step 6. After finishing him off, walk around enjoying you just made someone's day (burned them to smitherines.)

We've all learned that the Pyro has some crazy crap going through his head that is stupid at all angles. Like when he hugs someone, they burn to the ground and he just walks away wondering, where'd he go? Say you don't want to be stuck thinking everything is something else. You might want to buy something from the in-game store, or trade for one. And by something, I mean besides the regular Pyro mask. For example, I just sold a Vintage Foster's Facade on the Steam Community Market and someone bought it within two days! So try to be that person next time.

Thank you for reading this minuscule guide. I'm sorry if it really was minuscule, but my excuse is this is my first guide ever. And I thought some of you noobs out there would like it and find it useful. Even if you read this for a dare or for a time when you were bored, thanks again for reading it. And don't forget: BELIEVE IN MAGIC. And Like, Comment, and Subscribe. :D
