Edit:
original title: Two cards in midnight hunt that might pose a problem:
Both cards aren’t the problems i expected, thanks to @shteev aka @critman for testing.
Spell Queller and Sludgemonster (SQ and SM)
-Spellqueller disables the most expensive creature or support at ETB. There is no end to this disable, it lasts till the end of the game
-Sludgemonster turns a creature into a base 2/2 with no evergreens. There is no end to that either, it lasts till the end of the game
For both cards that means that destroying or exiling that card doesn’t end the effect, there is no other stipulation that will end the effect.
The only way to end the effect is to destroy your own creature or support (in the case of Spell Queller).
This essently is an efffect where there are almost no answers to: There are one or two black and one blue spells that allow destroying your own creature while destroying your own suppport (without trying to match it to death) is impossible.
This kind of effect doesn’t take into account that wie only have 3 creature slots and each creature after the first is considered to be the same creature (or support)
This can result in unfun and frustrating gameplay, where you can get bogged down without any type of answer.
I suggest to add something to the effect that would either undo it after SQ or SM leave play or that the effect is undone when reinforcing the affected creature or support.

Would you mind asking the dev team about this? maybe they can still add something to the cards before release?
