Pack Hunter

When you cast Pack Hunter, look at the top 4 cards of your library. You may cast a creature card with converted mana cost 3 or less from among them without paying its mana cost. Put the rest on the bottom of your library in any order, then repeat this process, instead with the top 2 cards of your library and a 1 cost creature.
When Pack Hunter dies, target player loses 3 life.
Just another fast predator in a brutal system.
