Nasus + Kindred Aristocrats

This deck uses strong sacrifice synergy (referred to as aristocrats in MTG) and removal tools to rapidly slay creatures, which buffs your Nasus and lets you maintain board control. The Undying is a persistent sacrifice trigger that also forces the opponent to choose between taking face damage (unblocked), adding to your slay count (chump blocking), or growing your threat (blocking and killing it). The finisher is simple--board control, followed by sticking a large Nasus and holding up Rite of Negation to prevent removal (alongside his natural spellshield). Alternately, you can just drop Ledros and chip them down with The Undying and removal tools.
