Master Chief Revised

{bold}Vigilance, Menace, Reach Master chief enters with 1 shield counter him. If Master Chief would be dealt combat damage and does not have a shield counter, Instead exile cards from the top of your library until you reveal a nonland card. If the mana value of that card is greater than the amount of combat damage, put a shield counter on him. Cards exiled this way are put onto the bottom of your library. {/bold}{/color#ffffff}
