mtg magic cards The 16 rarest and most expensive in the world Then and Now, Part 1
Description
Discounting activated abilities of of lands you control by 1 is pretty significant and makes cards like Nykthos, Shrine to Nyx (currently ruining lives in Pioneer in a mono-green deck, coincidentally) and Cabal Coffers that much easier to abuse

With a whopping seven power and defense, Sin becomes even more powerful thanks to his abilities

If you control all three, you may put a sticker on a nonland permanent you own
Maybe some of you deep blue mages out there can come up with ways to bust this open, as its eluding me
