Whenever a player sacrifices another permanent, put a +1/+1 counter on each creature you control.
Mazirek turns every sacrificed permanent—yours or an opponent's—into a board-wide pump, growing your whole team with each fodder you feed to sac outlets. You ramp into Mazirek, deploy cheap creatures and tokens, then trigger mass sacrifice off effects to swing for lethal or grind out value with drain and recursion. Each game plan revolves around chaining sacrifice triggers to snowball counters faster than opponents can stabilize.
Each sacrifice pumps your ENTIRE board, so a single mass-sac can create a lethal alpha strike out of nowhere
Triggers off any player's sacrifices, including their own fetchlands and downstream creatures
Black-green gives elite ramp, tutors, and recursion to assemble engines reliably
Rewards token strategies and aristocrats with double payoff (drain + counters)
Heavily commander-dependent—removing Mazirek shuts off the engine entirely
Counters are vulnerable to board wipes and don't grant evasion on their own
Slow to close without a free sac outlet and fodder online together
No card advantage built into the commander, so you must supply your own draw
