if you remember the "flip" cards of kami...these new double faced cards are just rip offs of that ability, designed to boost sales in WOTC sanctioned card sleeves, and extra "checklist" cards which im sure they will start selling on thier site, overall i agree 100%, they dropped the ball with this, if could have been so much more, but is nothing more then a rehashed "flip" thats been geared toward product sales
They can come to my table and find rookie cards for a dollar
Exploration plus Crucible of Worlds plus a landfall trigger that fills the graveyard doesnt feel like something that should have been printed on an individual card
Thus far, Doctor Who looks like a design slam dunk, and were excited to see the rest of the cards
If your deck actively cares about these, or you dont have other options, they can be pretty good
