Niko's Censure

This spell costs {1} less to cast for each card
you've drawn this turn.
Search target player's library for up to X cards
and exile them, where X is the number of cards
you've drawn this turn. Then that player
shuffles and creates a Shard token for each card
exiled this way. (They're enchantments with
"{2}, Sacrifice this enchantment: Scry 1, then draw a
card.")
