Interi's Library

When Interi's Library comes into play from your
hand, create a Learning counter ({t}, Sacrifice all Learning counters you control: Scry X where X is the number of Learning counters sacrificed).
At the beginning of your turn, double the
number of Learning counters you control.
Lord Interi was known for his enormous collection of
rare and out-of-print books on just about any subject imaginable.
