Nefarix, Death's Executioner

Trample, Menace
When Nefarix, Death's Executioner enters the battlefield, he deals damage equal to his power divided as you choose among any number of creatures.
Whenever a creature that Nefarix damaged would die, that creature's owner takes damage equal to its toughness.
"What an asset he could've been to my cause. A shame he has to die." -Lavotius, Demon King
