Glad you found something you like. :3 Now, stick to it until you get an item that catches your attention. When that happens, load up a training game with bots and test it out before you dive into a server with it.

Getting the basics of each weapon down is the key to getting better at using the class as a whole. For example:
Spy has 4 loadout slots: Revolver, Watch, Sapper, Knife. Learning how the revolvers require a cooldown before they are 100% accurate again, how the cloak can be recharged with ammo, and by enemy dispensers, when the best time to sap an engi's building are, and when to backstab people are all crucial parts to becoming a good spy. Oh, one final thing, disguising while cloaked makes you visible for a short period of time.
