mtg reveal the top card of your library Aye, Commander!: Manipulation in Commander Spell mastery — If there are two or more instant and/or sorcery cards in your graveyard Dark Confidant - Creature -

The combination of searching up a specific card and circumventing its mana cost is the devastating one-two punch on several unfair Magic cards (see Tinker and Stoneforge Mystic)

These locations add a whole new dimension of gameplay and a fresh new spin to every deck

Any combo that only needs one card and a Commander is fantastic, and being in a colour like black that doesn't normally get this sort of thing makes it even better

More mana, massive creatures, and bigger turns
