The card reads: Whenever one or more nontoken creatures you control die, create a green Fungus Dinosaur creature token with base power and toughness each equal to the total power of those creatures. If your creature dies, it just comes back to life as a mushroom dinosaur

You can fill your graveyard with Grisly Salvage and Mulch, draw cards with Night's Whisper and Harmonize, kill your opponent's creatures with Putrefy and Ob Nixilis Reignited, resurrect your dead creatures with Reanimate and Deadbridge Chant, or stymie your opponents with Arachnogenesis or Inscription of Abundance
