The Card of Reverse

Once per day as a reaction to being affected a
spell or any weapon attack, you may present this
card and speak "NO U".
Weapon attacks are magically redirected to the attacker.
Spells instead target the caster (or cast
centered on the caster).
If a Card of Reverse is used on another Card of Reverse, both cancel out and explode in the user's
hands dealing 8d6 points of fire damage.
