In my theoretical Chisei, Heart of Oceans EDH, this card is a star. Well, it would be if not for its colour identity (stupid rules and their making things not colourless…). Either way, this card is fun. It really screws with mono-coloured decks in a way that’s not too common in Magic. If you can find a way to keep the age counters off of it (like with Chisei or a Hex Parasite) it can pose major problems for your opponents for a long time. It’s a fun card that you really have to build a deck around for it to work.
Pros: Colour-shifted land mana production
Cons: Needs to be built around
