Levosian Cavalier

As long as Levosian Cavalier is your sovereign, creatures you control get +1/+1 and have haste. (Whenever a creature enters the battlefield under your control, you may have it become your sovereign if its
power is greater than your sovereign's or if you do not control a sovereign. You may only have a single
sovereign at a time.)
"Never falter. Never fear. Never forget."
-Levosian light cavalry motto
