Kaneshi, Predator of Fools

When Aneshi, Predator of Fools enters the battlefield, you may gain control of target
creature an opponent controls. If you do, then
that player mills cards until they find another
card that has the same creature type as the
creature you gained control of. They then may
put the card onto the battlefield without paying
the mana cost. Then each opponent loses 3 life.
If you did not gain control of a creature, you may
draw 3 cards and each opponents discards 3 cards.
