I understand that when you are creating your character in Adventurers League (AL) that you may only use options from the Player's Handbook and one other book (PHB+1). If I use Xanathar's Guide to Everything (XGtE) as my +1, is there any way for me to learn a cantrip from the Sword Coast Adventurer Guide (SCAG)?
Do any of these options (or something I missed) work in AL?
Leveling up and being allowed to choose a new cantrip
Taking a feat, such as Magic Initiate (PHB p 168) or Spell Sniper (PHB p 170)
Being a Pact of the Tome Warlock (PHB 108) where you can choose cantrips from other classes
While I think I am out of luck (the rule below seems to deny the options above), I am hoping that maybe there is some rule or FAQ answer that I have overlooked along the lines of this (for wizard spells or rituals):
Which Spells Can I Learn?
Spells are a class option; any new spells learned by advancing in a class or by feats are subject to PHB+1. Characters that prepare spells from a spellbook may copy spells even if those spells aren’t normally found in your character’s PHB+1.
I don't think the answer will depend on what class we are talking about (since cantrips aren't prepared from a spellbook), but I was specifically thinking about my warlock. However, I am still very interested to learn whether any class can manage this.
