Even my grandfather, who lost most of his fingers in a tragic chainsaw accident, can count the number of legacy playable planeswalkers on one hand (pretty much just Jace, the Mind Sculptor, Tezzeret, Agent of Bolas, and Liliana of the Veil, with apologies to Elspeth, Knight Errant and Tezzeret, the Seeker)
Specifying the bonus for exiling a creature is itself a cute reference to the fact that Ignis can cook various meals from the materials you get from killing creatures across XV s world, to boot
He does offer the additional upside of an ultimate that can devastate your opponents' boards and beef up your own presence, which probably explains why the planeswalker is the more played commander
Meanwhile, in Modern, a few players are slotting Stock Up into well-established archetypes like Atraxa and Grinding Station
I love that we have three decks instead of two, which adds that extra bit of replayability instead of just two dueling decks
