Partner with Regna, the Redeemer (When this creature enters, target player may put Regna into their hand from their library, then shuffle.)
, Sacrifice X creatures: Target player draws X cards and gains X life. Put X +1/+1 counters on Krav.
Krav is a mono-black (or B/W with Regna) aristocrats payoff that turns sacrificed creatures into card draw, life gain, and a growing beater. Flood the board with cheap and token creatures, then activate Krav to draw cards, gain life, and pile +1/+1 counters to swing for lethal commander damage. You grind value off death triggers while building toward a single explosive sacrifice turn.
Built-in card advantage engine that refuels your hand off otherwise spent creatures
Krav grows huge fast, threatening commander-damage kills and pairing perfectly with aristocrats drain effects
Lifegain from the activated ability keeps you out of range and fuels life-payment cards
Partner with Regna gives access to white token-makers and a second body to sacrifice into
Activated ability requires creatures on board, so heavy creature removal and board wipes hurt badly
Krav himself does nothing the turn he enters and needs a sac outlet's fodder to function
Mono-black struggles with enchantment/artifact removal and noncreature threats
Telegraphed strategy invites targeted removal and graveyard hate
