Janos, Alleyway Hustler

Luck X, where X is a number of your choice. (At
the beginning of your upkeep, you may shuffle your
library and reveal the top card of it. If that card's
converted mana cost is X, put it into your hand.)
Reveal a card from you hand: Counter target spell
with converted mana cost equal to the card you
revealed this way. Put a -1/-1 counter on Janos,
Alleyway Hustler.
