I am having a problem with the card Moonshadow. The rules text on the card says "Whenever one or more permanent cards are put into your graveyard from anywhere while this creature has a -1/-1 counter on it, remove a -1/-1 counter from this creature." I am playing on android. To reproduce this bug, you need to have Moonshadow in play with at least one -1/-1 counter on it and have a land go into the graveyard which should remove a -1/-1 counter. Note: This card does not exclude lands as permanents per the rules text. The expectation is that the lands going into the graveyard would reduce the amount of -1/-1 counters on Moonshadow. I don't know of any workaround.
