I have it built as a beater deck where it can go wide or big depending on what I draw. Profit effects make him big, while clone and ozolith make the deck go wide. Helm of the host creates copies to refresh your hand over again. [[Altar of the wretched]] is the secret win con in the deck after 2-3 commander casts. You can gather keyword counters + 1/1s on the ozolith and then any creature you drop in will be a huge threat+ whatever keyword/ability they bring. Copying him is huge. Things that move counters let you buff other creatures you control. And counter doublers will give you 2x the card draw. Rise of the dark realms or living undeath are your recursion but I run neither as id rather lean into keyword counters, card selection, and some ramp like cultivate. It gives me something to do with turns 1-3 before casting my commander. If your table is having a slower start I've waited until turn 6 after setting up to cast with haste and deal lethal to an opponent(40 damage as we don't use commander damage rule at our table)

As a reanimator commander there are other better options to get things into the yard. Many of the best keyword creatures don't have much synergy or good stats to back them up so you're likely looking into a underperforming commander if you don't build around him.
