what if the permanent was destroyed if you ever don't have enough quanta to pay for its upkeep, making you watch your quanta levels
Thats essentially what is meant by "Absorbs
" . I.e. every turn it consumes 1
quanta. If the player doesn't have enough, this card gets destroyed (just like the card Flood|Innundate for water that is in the game now)
I like this card but the buff would be removed upon the destruction of this card right?
Yes, if the card gets destroyed, the buff disappears. For the purposes of the +1|+2 buff for creatures near malignant cells, it would act just like nightfall / eclipse.
Any poison dealt to the opponent (upped version) would still remain of course.
