Legendary Enchantment - Background (Rare)
Commander creatures you own have "Whenever one or more creatures you control deal combat damage to a player, goad target creature that player controls." You don't know what shyness is. You love the spotlight and they love you.
Myriad and the general spreading around of attacks is a major theme for Red in this set, so making it a goad requirement was bound to happen. Turns out "don't let the haters get you down" could also mean having them beat each other up in adoration of you.
