Need some help to get back into Halo

It’s been a long time since I played halo at online so I’m really rusty. I need help getting back into the swing of game play and I need a few good players to help with that. I usually get on daily and but I get on around 11:30 or 12 at night with some irregularities here and there. When I say help I mean help in halo CE, 2, 3, and 4. I wanna get back to where I used to be, or possibly better if at all possible. So if you wanna help out message me on here or on Xbox One. The only things I ask is that you have a mic and are 18 or older. And if you wanna play custom games after or with me period then add me on Xbox One.
