Grenzo, Dungeon Warden

Grenzo, Dungeon Warden is a self-mill engine that rewards you for playing small creatures. You enter the game with X counters, then repeatedly mill cards from the bottom of your library using Grenzo's activated ability. Every creature you hit becomes a free board presence as long as its power doesn't exceed Grenzo's current toughness—so you naturally want creatures that are small or scale with your commander's size.

The deck is built around stacking your library so Grenzo hits creatures consistently. Cards that move creatures to the bottom of your deck, artificially large starting power on Grenzo, and effects that give Grenzo +1/+1 counters all help you cast bigger threats for free. Once you've generated enough creatures and board presence, you either bash through for combat damage or pivot into sacrifice synergies, using your creatures as fuel for aristocrat effects that drain opponents or generate value.

This is a tempo-focused deck that wins through consistent creature generation and tempo advantage. You're rarely racing—instead, you're grinding out value every turn while Grenzo mills your deck into creatures you can play immediately.
