Let's first start out with the good about the set, which outnumbers the bad. First of all, a lot of the new minis are very good looking, especially the ones that make use of the clear plastic. Noteworthy minis include the Angel of Vengeance, the Blazing Skeleton, Doresain, the Ghoul King, the Death Titan, the Fire Titan, and others. Another good aspect of the set is that it adds epic play back into the game. The product is moderately priced, being fair in my opinion, if you buy it here or somewhere else for less than its retail price. The cards keep their fairly good layout and sharp appearance with the new epic cards being a mustard color rather than a maroon one. Its an odd choice in colors but it works. There are a lot of neat ideas in this set, many of which I hope get carried into other sets.
Now on to the bad. The first bad thing is the large amount of repeats this set has. While they are slightly different, there are repeats from other sets like the Boneclaw Impaler, the Elder Red Dragon, the Xorn Ravager, a third Owlbear incarnation, another Roper, and many others. Another thing is the fact that there are no dragonborn in this set that are not rares, making players who are seeking a dragonborn mini to have to get lucky, buy many packs, or spend $$ on singles. Lastly, the paint job on a lot of the minis are terrible (Storm Giant Thunderer is abhorrent). Plastic is still lower quality than some older sets.
If I could I would have given this product a 3.5, but I can't so I am giving it a 4. The product is generally solid overall, but many of the aspects of former sets that made them truly good falls short here.
