That's a very neat analysis of the card value for this legendary summoner. In my opinion this card will be sold out in minutes if not seconds. Probably some whales will get most of them and then rent out or resell them. It might be possible that it will be possible to buy the card at a later stage in the splinterlands market.
I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post! 
I agree it'll probably sell in minutes... That's a good thing :)
