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.

I have this at 1.5, and have no problem maindecking it. But then, I'm a control freak 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.

1.5 is spot on for this.
