Are the systematic letter swaps in the name intentional? (It's in both upped and unupped, in upped in both words, names in the table match only the title is written normally)
Its a bit strange to give a permanent that does nothing at first such a high cost; I would raise ability cost and lower the initial cost (I would see 3
and 3
unupped and 2
upped ability cost fit). Having both CC and healing in the same card might make it a bit too easy to stall with it as this card gives you basically all you need in a stall (albeit being a bit inefficient and unusually slow).
Edit: Also I dont think the healing should stack, the quicker accumulation of poison should be good enough (balance around it if necessary, the above suggested cost was given with healing stacking in mind); the card already demands you to build around it as it is, let's not punish players for using/drawing few copies of it further.
