Judas the Betrayer

First Strike.

When Judas the Betrayer enters the battlefield, put a kill counter on Jesus Christ, Son of God (If he is on the field) and add one counter at each upkeep. When the kill counter reaches 3, exile Jesus Christ, Son of God. If Judas the Betrayer is moved to the graveyard, or exile, from anywhere, remove all kill counters on Jesus.
