I have played Bx colorless more than almost any deck, but still haven't mained this. Would you play 1 mana to cycle? Sure. Would you pay 1 for a 1/1 scion you can sac for 1? Maybe... Would you pay 1 to ingest 1? Nope. Sorta feel like this should cost 2 or cost 4 and draw 2. I guess it's basically exactly a 22nd card... pretty sure I always play 18th land over it, and in some decks it will be worse than 19th land.
If you want to be the attacker, you don't want it. Another fine example of a card GB wants, and RB doesn't care about.
