Best way to prevent instant death :
: Orphic Theory (1xp)
: Delay the Inevitable (0xp)
: Alter Fate (1 or 3xp) or Devil's Luck (1xp)
: Deny Existence (0xp)
: nothing trivial, maybe Cheat Death (5xp)
Orphic Theory allows you to ignore the card text before it triggers. Use it within your investigation phase then draw the last cards of your deck. Beyond the Veil won't trigger, meaning it will stay in your threat area. But you're temporarily safe.
Delay the Inevitable can only be played during your turn so be cautious. Play it then draw the last cards so it will trigger immediately. Then your discard pile is shuffled into your deck during upkeep phase, before you have a chance to draw it again (and die instantly).
Alter Fate: same thing, use it during your turn then draw the last card(s). The 3 xp version won't cost an action. Devil's Luck is more efficient, but it will cost you 1 xp each time it is used if you want it back (unless you bought Déjà Vu).
