Mana Ramp This deck is mana-hungry, so mana ramp is incredibly important
Its status as one of the lowest mana value cards on the list also means you can get it out early, putting up the barricade and setting up your engine before many players will be able to rival it
I also like this as a free sacrifice outlet in Commander decks that need one, since you can equip the Bloodghast and then unequip it to kill it, but a simpler way to do that is with the Hauberk which can sacrifice anything to give +4/+2 to a dork you control, like your Commander
I'm a decent Magic player and I can build a pretty good Commander deck but I'm also well aware that I've got my own blind spots and deck-building foibles that affect how I play the game
Not all graveyard hate is all-or-nothing, either
Force of Will's mana value is always 5, no matter what you paid to cast it
