Trading in 3 mana (2 to activate and the opportunity cost of tapping Fountainport for colorless) and a token for one card isnt the most efficient sac-for-card trade that there is, but youre paying a tax for the modality of all the other abilities and the fact that its a land, not a creature or something
You can fill your army with artifact creatures like Kuldotha Forgemaster, Platinum Angel, and Ornithopter of Paradise, or rely on face down creatures like morphs and disguise threats
That said, there are still plenty of ways to power it out in Mono-Black, including ritual spells and generic mana ramp like Ancient Tomb and Mana Vault
