Let me start off by saying this is in NO way, shape, or form about banning a card that does not need to be banned. All I'm proposing is that PotM does gain the keyword "Terrain".
There's already been many people confused by the name of the card in comparison to the type of card it is. A "path" is about as terrain-sounding as a name gets. I personally tried to Tower of Souls one of my copies in last night, like an idiot, lol. (Which by the way, would have been well-costed as I have to remove ToS from the game, something that currently cannot be brought back in standard.)
Naming aside, another reason I propose this is because I think it would encourage more people to play terrains. They're a fun enough keyword, and obviously important enough that they had a ruling change to them not too long ago. With all the talk I've been seeing about assets being hard to handle, and this card being considered an auto-include to MOST decks, by most people, I think this would be an appropriate answer to a card that is quite powerful yet NOT banworthy.
Let me know what you think. As always, let's please be civilized about this, I can respect your opinion whether you agree or not. I'd just like you all to share your reasoning behind your decision. Thanks.
