I need advice

Soooo I want to pull Von Lycaon (For obvious reasons lmao) and idk if I should pull on the stable channel or the exclusive channel

Pulling for Von Lycaon is quite rare cause theres like 12 S ranks including the weapons but if I want to pull on the exclusive channel Ill have to pray that I lose the 50/50 and get Von Lycaon

what do I do? (Im kinda new lol.)
