You have to largely complete the Seasonal Challenge tower to get that Sub skin.
I failed the TYM at the end and still had it unlocked, whether you get awarded it after a lesser number of challenges I don't know, but we do know the final TYM isn't required. My assumption would be be the first 17 floors though (I wouldn't want to quit half way through just to keep testing the theory).
If you use the konsumable that makes you impervious to projectiles, you'll be invincible for the Survive challenges. The rest is just a grind of either a strong talisman projectile or strong talisman armor, it's not hard, just boring.
