Other Demons, Devils, Imps, and Tieflings you control get +1/+1 and have lifelink.
At the beginning of each end step, if a creature card was put into your graveyard from anywhere this turn, create a 1/1 red Devil creature token with "When this token dies, it deals 1 damage to any target."
Build a wide tribal board of Demons, Devils, Imps, and Tieflings that all hit harder and drain life via lifelink, while Raphael's end-step trigger generates a steady stream of pinging Devil tokens whenever a creature dies. You aim to overwhelm the table with an anthem-boosted aggressive board backed by aristocrats-style attrition, closing through combat damage and incremental drain/burn.
Built-in anthem (+1/+1 and lifelink) makes even small tokens threatening and stabilizes your life total
Free Devil token generation off any creature dying fuels both blockers and reach damage
Strong synergy with sacrifice and recursion engines that constantly trip the end-step trigger
Rakdos gives access to elite removal, reanimation, and aggressive tribal payoffs
Heavily commander-dependent; losing Raphael shuts off the anthem and token engine
Token Devils are individually fragile and vulnerable to board wipes
Tribal payoffs are narrow, so off-type creatures get no bonus
No card advantage built in—can run out of gas without dedicated draw engines
