You need to convince your opponents that yes, you actually do need that Bolas's Citadel to save them and yes, you do need the Damnation in your graveyard to wipe the board
It reminds me of Whisper Squad, which looked really weak at first, but then youd end up playing against someone with seven of them and the game becomes all about them
Not only is this the best use of red mana in the ramp deck it is a card that doesn't hurt you much at all should you not be able to fix your red
The deck then adds a ton of different wrath effects (Star of Extinction, Razia, Austere Command, Blasphemous Act, Day of Judgment, etc) to deal with any threats your opponents might be able to cast prior to you repeatedly wiping the board of lands
Its near and dear to EDH players playing any sort of deck that has good ETB creatures or commanders that rely on ETB triggers/blink strategies
Target creature can't be blocked this turn
