Chancellor of the Mulligan

Artifact Creature — Phyrexian Construct7/7

You may reveal this card from your opening hand. If you do, at the beginning of the first upkeep, shuffle it into your library and draw a card. Menace When Chancellor of the Mulligan enters the battlefield, draw three cards. When you do, any number of target players mulligan. (They shuffle their hand into their library, then draw that many cards and put one of them on the bottom of their library.)
