Wilhelt, the Rotcleaver Wilhelt, the Rotcleaver is the zombie commander of choice if you want your commander to be a zombie (I think theres a strong argument for Gisa and Geralf as the ideal choice, but I digress)
I recommend not having too many blanks
Legendary Creature - Artificer Angel Color tag templates(None) Wyleth, Soul of Steel Trample Whenever Wyleth attacks, draw a card for each Aura and Equipment attached to it
Nethroi, Apex of Death plays as a combo deck using creatures with negative power, like Scourge of the Skyclaves, to reanimate an unreasonable number of creatures
These decks can function on just a few sources of mana and want to draw the bare minimum number of lands needed to cast a few cheap spells each turn
Simply put, it still doesn't require much effort to pick up again after time away and several expansions in
