Assaya, Keeper of the Infinite

When Assaya, Keeper of the Infinite enters the battlefield, for each archive you own, create a
token that's a copy of it.
Whenever a triggered ability of a library you own
would trigger one or more times, that ability
triggers that many times plus one instead.
"The Infinite Aethenaeum is a great task for one such
as I, but the reward is well worth the effort."
