Life // Death Adding Life // Death to this ranking feels like cheating since Ive never seen anybody use it as anything but a 2-mana Reanimate, but 2 mana and some life to get a threat of any size into play is still a fantastic card
Creatures and nonbasic lands your opponents control enter tapped
But, when either of those cards is in play with a Location at the same time, everything cares about Locations
Wed definitely recommend you just put your favorite instant and sorcery spells in the deck, but its also worth putting in every single card that puts nonland permanents back in their hand like Consuming Tide, and also those that destroy nonland creatures like Planar Outburst
Krenko, Mob Boss, Zada, Hedron Grinder, and a few others on this list are very popular commanders online, as goblins is one of the best supported types in all of MTG
If you want a one-mana 2/2 creature in black, try Diregraf Ghoul, Carnophage, Sarcomancy, or Vampire Lacerator
