Some things that you often notice? Sequences of events that always turn out the same way? Pre game rituals?

Here are some of mine:

Spike is cursed. If I have spike I WILL die a quick and embarrassing death.

Enemy guns are also cursed. If I pick up someone else's gun (moreso if it's a cool skin), next round I WILL die a quick and embarrassing death and immediately lose the skin. (There is a 0.001% chance the skin is blessed instead and I pop off though)

Picking cypher basically guarantees I start on attacking side

Setting up a site (mostly with cypher/killjoy) means the enemy team will always push the other point.

There is always someone with a shotgun inside every smoke. Always.
