WotC loves throwing a card in now and again with a huge drawback and non-obvious power level. A card that to some looks completely terrible, and to others totally busted… somehow. It used to be more common that cards had outright downside, but these days when you see a downside it usually intentionally pushes a specific deckbuilding direction. Demonic Pact is exactly such a card.
If you can survive three turns of activating this card (and stop the fourth from happening) then you get some pretty good value for your four mana. It’s a little slow, but the power is there and the interaction with current all-star Dromoka’s Command is worth considering.
When I look at Demonic Pact, I’m immediately reminded of Abyssal Persecutor. It was a card that saw fringe success, though even in the occasions when it was winning was avoided by most players, likely due to the commonality of risk aversion.
Demonic Pact looks to have constructed potential, but we’ll have to wait and see. Do you think it will make splashes, or are the downsides too great?
