At April´s fools day, Mtgpq account in Facebook publish this PW. I suppose this started as a joke, but in my opinion it would be very interesting if they release it with a little changes to be more playable.
His 3rd ability could be like it is but with most cost and instead loosing the game (wich means an autolose with a misclick) and also a fast winning without achieving objetives if opponent use it. But changing lose the game by your mana bonuses become -3 in your next turn for example, or also your cards become disabled at the begining of your next turn and also bonus malus (if the ability remains at 13 cost).
Legacy:
Torment of scarabs
Cruel reality
Overwhelming Splendor
Curse of predation
Fraying sanity
The way they work doesn’t match with the unluckiest second skill though … Because they dont affect the owner of the curse but his oponent instead.
Considering the supports available, his second skill could be interesting if it worked.
