 Library Graveyard.     Ub

World Enchantment Land 

Except for the first card drawn by a player on their turn, if a card would leave a library, exile it facedown instead.

10, t, exile Library Graveyard: Mill all libraries. Shuffle Library Graveyard with all cards exiled by Library Graveyard. Put them in a facedown pile. This is each player's library until the last card is drawn, then players shuffle all exiled cards they own into their libraries. Any player may use this ability.  (:

2, t, sacrifice a permanent that shares a color (including colorless) with Hank: Deal 1 damage to permanents of the color of your choice (or colorless). For each damage dealt, deal 1 to that permanent's controller. If a player controls no permanents of that color (or colorless) they sacrifice a permanent.
