Dragonclaw Strike
There are plenty of payoffs for having a full graveyard, such as Battlefield Butcher draining your opponents life, Ashnod, Flesh Mechanist using them as fodder to make Zombie tokens, Gaeas Courser giving you card draw when you attack, and Gnarlroot Pallbearer being a potential game-winner by buffing something by the number of creatures in your graveyard
Commanders with cost reduction that eat into the commander tax are pretty powerful
Would you say you are a picky grader
I have some bias because all four of them either focus on mechanics I find really fun (monarch, politics and voting, and Food) or play into archetypes I already really liked (Grixis reanimation and spellslinger)
Two boardwipe cards of their own, Winds of Rath and Valiant Endeavor, offer their own way to turn the game around
