MAGIC: THE GATHERING
|Edition:||Modern Masters 2015|
If Leyline of Sanctity is in your opening hand, you may begin the game with it on the battlefield.
You have hexproof. (You can't be the target of spells or abilities your opponents control.)
Leyline of Sanctity shuts down discard, burn spells, a variety of combos, and some cards you wouldn't expect, like Gifts Ungiven. You don't even have to play white mana, just run four and hope it's in your opening hand.
