(This was created as context for Challenge # 037.)

Trying to understand the card: Is it deliberate that the discards are part of the effect, not the cost? Surely not, because your hand is private, so I could activate it and just say "Oops, looks like I've not got any creature cards in hand again..."

That is an error, and thank you for catching it. I'm editing it as we speak. Also, I apologize for not earmarking all these cards for Challenge # 037. That was obviously a load of work, and it didn't occur to me that I had one more thing to do. I'll probably go around and earmark them later.

I'm not really sure how much this adds. I guess it's part of the staying power; and as long as you leave at least one counterpot in your graveyard you're ok.

Funny thing is, while this card doesn't specifically add anything to the deck besides staying power, I consider this to be the most unrealistic of the cards in boney. It's just too good... I know Tortured Existence used to be a common, but it seems too comborific for today's standards. A lot of these cards are "reasonable, if you add a to them." This might still be unreasonable, even if you added a to both activation costs. Ah, well. It flies under the radar in this challenge, I suppose.

Oh, it's evil and awesome - but not particularly in this deck; which isn't drawing a tonne of cards or recursing its own cards much.

Yeah, I thought this would massively help the consistency, (which is powerful in any deck), but not help this one specifically.

Come to think of it, it's a source of card advantage with Counter Ball -- discard the ball, return a creature, then use the counter ball from the graveyard.

Oh - Jack's comment makes me realise something, which is that this card provides Boney's only option for surprise countermagic. Counter Ball normally needs sorcery-speed investment as a warning to the opponent that some countering might happen. This card allows you to dump it in the bin at instant speed.
