Thraben Inspector. In the same way as the previous commander, this one also creates many tokens, in addition to generating several + 1 / + 1 counters. She gains a lot of life, in addition to ramping
Avacyn Pilgrimmaking the deck faster and more lethal. The one-cmc elves that generate mana (aka dorks) are an excellent option. It can be a little fragile as it will generally not adopt as many defenses. It may have some removals, but do not add as many, as it may be counterinteractive with you gameplan. With Narfi, the most suitable is a zombie deck, as it has a static ability that gives all zombies and also snow creatures with +1/ +1. Itsactivated ability has snow cost, so snow lands must be used, and it is also a great opportunity to use
Arcum's Astrolabe, in addition to the dual snow land of the Dimir colors.
Shepherd of Rotis great on this deck, as is
Carrion Feeder, who can act as the deck's finisher. Be sure when playing with this deck, you will easily be the target of everyone at the table. A commander who places two poison counters when attacking a player if that creature has Deathtouch. It's incredible, and not at all difficult to build around. It just needs many creatures with Deathtouch and evasion, or ways to evade them. Good cards for this deck are
Blight Mamba, which if combined with the Druid, will deal its infect damage and add poison counters too.
