Riftbound Unit: Veteran Poro. [Weaponmaster]
Riftbound Unit: Vayne, Hunter. [Assault 3] (+3 [S] while I'm an attacker.) If an opponent controls a battlefield, I enter ready. When I conquer, you may pay [1] to return me to my owner's hand.
Riftbound Unit: Peak Guardian. When you play me, buff me. Then, if I am at a battlefield, buff all other friendly units there. (To buff a unit, give it a +1 [S] buff if it doesn't already have one.)
