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
Likewise, Imperial Tombs of Necrovalley can only be activated if a Gravekeepers monster AND Necrovalley are on the Field
If it isn't the first time, you can turn one of your face-down permanents back up for free
You can then quickly energize any Pokmon you bring into your hand with the Crimson Flame Pillar- GX attack, which lets you attach 5 basic Energy cards from your discard pile to your Pokmon
This is a very strong start and we can assume that single pip powerful cards are going to be playable in almost any deck - as long as you are interested in them
