Every good botanist needs a list of ingredients, and here are Witherbloom's newest reagents: Gorma, the Gullet is yet another horrific and gross black-green legendary Frog commander that eats your creatures for a benefit, giving +1/+1 counters to each creature that enters based on how many creatures died under your control that turn Stensian Sanguinist prepares Exsanguinate (notably the only non-Reserved List, non-1990s prepared spell in this cycle) by dealing damage with a creature that gains deathtouch from the Sanguinist's trigger on attacks Ominous Harvest sports the classic Future Sight keyword of gravestorm, and is only the third card in the entire game with that ability Immoral Bargain may have finally broken a glass ceiling on premium removal in black-green, affording go-wide decks to deal with almost any amount of problematic nonland permanents while being a sacrifice outlet at the same time Turbulent Fen is the only new land to come from this precon, but it's still a welcome inclusion This may be the only deck of the bunch that provoked a tepid response

Topiary Panther
