Theres also a space for legends and +1/+1 counters this might be a good Golgari commander for, including cards like Reyhan, Last of the Abzan, Grakmaw, Skyclave Ravager, Polukranos, Unchained, Rishkar, Peema Renegade, Kodama of the West Tree, Renata, Called to the Hunt, and plenty of others
Turn 4 kills were easy, and if that failed, the games rarely went past turn 5
This meant that the player only needed as few as 2 knockouts to win the game using Gengar and Lost World
each of the five serves one of five countries
What about in Modern or Pioneer
I rarely play storm or decks where proliferating matters, but I can absolutely imagine this card putting in a lot of work for someone that is used to playing both of those and causing an absolutely overwhelming amount of value at instant speed
