While the front side is good enough to see play on its own, the fact that it only has four defense counters makes it relatively easy to flip (a single Sheoldred, the Apocalypse attack gets the job done), and the backside offers a very powerful creature that can defeat a battle or kill a planeswalker each turn while potentially generating card advantage as well
The more annoying aspect is with the DLCs, which give out cards that cant be obtained in the base game, and sometimes offer way too little bonus content for the 5$ price tag of each
