Need help in a LAN tourney

hey guys, i’ve got a LAN coming up with players from gold, platinum, emerald, diamond up to masters. i’m a gold top laner, so i’m on the lower end, but i did beat an emerald top in scrims with Renekton so i know i can hold my own sometimes.

my best champs are Renekton, Darius, and Morde (AP). i can also play Sion, Ornn, Ambessa, but not at the same level, more like i won’t int rather than actually win lane.

i’m stuck between sticking to my comfort picks or just one tricking a tank and playing safe/weakside. my goal is basically not to be a liability or go 0/11, i’m fine going even and being useful in teamfights.

should i trust my mains or just play tanks for consistency?
