The math here isn't really correct. You're not spending $10k for one maxed common. You're spending $10k for $10k of SPS + 1 maxed common. You aren't losing the value of the SPS in this, and no one will price the card that way.
Right now, there are like 400M sps staked, so there will be lik 400k BCX of this card. Guess what else has 400k BCX? Salty Bear. Guess what salty bear's price is? $0.23. Yes, this card will cost an extra $0.1 since you need a voucher too, so I predict it'll land somewhere around $0.3 (plus or minus depending on how good it is).
