UR Symbiote Venom:
Ultra Rare Venom meets a need that players have been waiting to be filled, an acceptably powerful UR Bruiser card. Although players might look at him and say 'hey, he's pretty much an Iron Man with less frequent proc rates!' he does allow bruisers to get rid of those UR+ Thors in the core of their deck. That and the fact he's Venom and extremely limited puts his price somewhere around 300+. Personally though, I wouldn't pay over 200 for him because lets face it, he's an Iron Man.
SSR Wall-Crawler Spider-Man:
Seriously...another Spider-Man? Don't have enough of those. And it does what? Oh, decreases Bruiser attack and defense...yeah...that's not useless at all. Lets face it...this card is just bad. It helps you defend against the weakest alignment offensively and defensively. I bet it will sell pretty solid for 10PP but lets be honest, it's worth 7PP at most.
SR Secret Veteran Arachne:
Actually she's really good for an SR card and possibly the best SR speed attack card now. Her pure boost to speed attack and her future wall breaker event ability makes her a pretty nice card. Unfortunately her abundance will bring down the price. Realistically 3-4 PP each would be a reasonable amount of PP.
R All Seeing Doctor Strange:
Lets be honest. He really has no value. Rares just are nice stepping stones for low level players but otherwise are used to skill up cards.
On a side note. Pretty much every SR quality card is worth 1-2PP each at this point and in a month will probably all just be worth 1PP each.
