BRG grinds with sacrifice and value creatures like The Sackville-Bagginses and Rottenmouth Viper plus discard-oriented removal in Requiting Hex and Stir Up Trouble, so Duress strips their own Strategic Betrayal or Duress before it can disrupt our plan. Bloodthirsty Conqueror is a flying deathtouch threat that gains us life whenever an opponent loses life, synergizing with our incidental damage and surviving combat against most of their ground creatures. Erode is a reasonable removal spell already, but we trim two copies since it also ramps them into their own lands via the search clause, which is not ideal against a grindy value deck; Get Lost is a lower priority removal spell to free up slots for disruption. Keep the lifegain core intact since Amalia and Lunar Convocation grind better than their one-for-one value creatures long-term.
