As others have mentioned, Demonic Pact's modes aren't consistent with how they visually update to show which modes have already been selected, and which are still imminent.

There are a few posts about this visual bug already, and I want to make sure that this is receiving proper attention. In one of the posts, there was a response that said something like, it is the player's responsibility to keep track of which modes have already been selected. If that is WotC's intention on the card's behavior, that is perfectly ok, but there must be visual consistency.

Having some modes grey'd out and not others is problematic. Especially when playing against this card and your opponent is using multiples of it. You use your removal on the one you think is most relevant only to find out you picked wrong because of visual inconsistency.

I wonder if the bug is a result of having multiples on the battlefield? Either way, would very much like to see this corrected one way or another. Here is a link to a 10s clip where it looks like there are multiple modes still left on the card, but that wasn't the case. https://medal.tv/games/mtg-arena/clips/leIBY6CIgmTL-4ULj?invite=cr-MSx6elEsMjA5NzYxMjAx&v=10

Again, if WotC determines that it is the player's responsibility to keep track of this, I am totally fine with that. Just be consistent with how that is visually displayed.
