Oath of Adhaman

When Oath of Adhaman enters the battlefield, create a 3/3 White and Red Angel creature token with flying and vigilance.
At the end of every turn, if you control a Planeswalker, draw X cards or deal X damage to target creature or player, where X is the highest converted mana cost among noncreature spells that were cast this turn.
"To protect worlds from mine's fate, I will keep watch."
