Lyre, The Ledger Keeper

At the beginning of your upkeep, scry X. Then,
you may draw up to X cards, and sacrifice that
many Treasure tokens. X equals the number of
Treasures you control, minus the number of
opponents you have. X can't be less than zero.
If an effect would create one or more Treasure
tokens under your control, it creates that many
plus one of those tokens instead.
{t}: Scry X.
