You misunderstand Shorecaster's ability - it will exile Shorecaster, then - before anything else happens - return it to the battlefield. Perilous Vault will either resolve before or after that, but one way or another, your Shorecaster will be exiled by Perilous Vault's ability.

The way I'm stacking the triggers from vault and shorecrasher would be so that vaults exile ability resolves before shorecrashers. Shorecrasher would be exiled by the vault, not by its own ability. I was thinking its ability might still resolve after vault and bring it back since shorecrasher would see itself in exile and return.

Ok, I understand how it works now. It did seem too good to be true, but that's how cards broken. Thank you both.

There are no triggers involved here. These are activated abilities.

Just as a note, When a card refers to itself by name it is a shorthand for saying "This permanent" and if an ability refers to a permanent on the battlefield by name it requires that permanent to still be there
