Im looking forward to seeing if they add a couple more Desert related cards later in the week, but even without any more, there's plenty to work with as of right now
Their value lies strictly in visual presentation and rarity, not in competitive advantage
However, they won't be affected by the other effect and will untap as normal during their controllers' untap steps
The development involves dozens of people helping to design, draw, and test cards that, hopefully, will hold a special place in players hearts
In ascending order you would walk through Japanese, then Chinese, then Korean and Russian in terms of scarcity and value for US collectors
This would also be the time to use Craigslist or Offerup or whatever selling methodology you like
