Hoping that after Champions 2023 they will do custom skin for winning teams. Hypothetically, if Fnatic were to win again:

First scenario:

One Gun Skin (Vandal/Phantom) + FNC (Gun Buddy, Spray and Title)
Level 1 - Base Skin
Level 2 - Inspect and Kill Effect
Level 3 - Finisher
Level 4 - Champion's Aura

Variants: Custom Finisher for each member of the roster with their signitures (Boaster's might be him twerking or dancing to Twice's or New Jeans' choreography)

Second scenario:

Each player gets to pick a specific weapon they like (Vandal/Phantom) + FNC (Gun Buddy, Spray and Title).

Leo - Frenzy
Alfajer - Phantom
Derke - Operator
Chronicle - Knife
Boaster - Odin

Each would have custom finisher but no variants. (Although these would cost too much for my wallet to handle)
