If Cycling/Discard Matters is a thing in your cube, I think this is perfect. Drawing it again just to cycle it is pretty good in such a deck, and you will draw it often if you keep cycling. Also getting a pretty strong finisher is bonus, and I find it way more interesting than
Eternal Dragon.
I think this is a very good control finisher. Returning it to your hand by cards like
Genesis,
Phyrexian Reclamation etc., this will always be a 1R hasty uncounterable 8/8 trampler that cantrips if you've managed to cycle it enough. I really like that you have to do work for it, but gain something really cool and potentially strong, if you adjust your drafting and deckbuilding.
