Trivia & titles

Ainz (Sovereign) was the secret of Era Twelve.
He was the first Era secret that a Shiny Stone cannot be used on, leaving his shiny among the rarest in the game.
The Protector is the only other Era card with that restriction, added six Eras later.
Pulling Ainz (Sovereign) grants you Era 12 - Hunter.
Pulling a shiny King of Undead (SUPREME) grants you Era 12 - Shiny Hunter.
