Spirit of the Night
A summon-creature payoff from an era when nine mana was supposed to buy you something that ended the game on contact, and this one nearly does: every evasion and aggression keyword stacked onto a single body. Flying clears the ground, trample punishes chump blocks, haste means the cost translates immediately into damage rather than a turn of waiting, and the attack-only first strike makes the 6/5 effectively unkillable in combat the turn it swings. Protection from black is the load-bearing line, and it tells you what the card was built to fight: a format saturated with black removal and black creatures, the very deck most likely to be casting a triple-black demon in the first place. The protection clause means mirror-match opponents cannot Terror it, cannot block it with their own fatties, cannot enchant it down with black auras. It is a finisher engineered to be self-protecting against the exact color that wants to play it. The design philosophy here is pure top-end maximalism, the opposite of the carefully restricted bombs that came later: no drawback, no upkeep tax, no sacrifice clause, just a pile of abilities priced at a number that assumed you would rarely reach it. What dates the card is not the keywords but the cost; nine mana in mono-black has always been the kind of investment that asks the rest of the deck to keep you alive long enough to make it.
