Kendall Roy, Born to Succeed

First Strike
Dethrone (Whenever it attacks the player with
the most life or tied for most life, put a +1/+1 counter
on it.)
Whenever this creature's Dethrone ability
triggers, you may search your library for an
artifact or enchantment card with mana value
4 or less, reveal it, put that card into your hand,
then shuffle. When you do, discard a card at
random from your hand.
