Since there is no one reporting on massive amount of cards... I guess I'll do it since they seems so off to me...
Short bow, boneyard, aflatoxin, colossal dragon, graviton slavager, firefly, immortal, phase dragons : unused and not of much power... don't jacked the price at all if we want a slim chance that they are in war!
Maxwell demon: useless outside of entropy and a minor threat when used.. not worth such a big raise... 40 is more then enough.
Abomination: great for entropy rush or entropy duo with disco... was worth it's price, maybe 70 would have been ok.
Dissip shield: worth a raise since you build the entropy stall around it... but it's so easy to counter, it's not worth 70 at all... maybe 50.
Lycanthrope: great for entropy/dark duo and most nova deck, worth more then 70 for sure... maybe 90.
Antimatter: cost is too high to be such a big threat especially when expected.. price of 70 is about right.
Pandemonium: Great CC to clean up the board and stay hidden behind walls. It is totally worth 90-100
purple nymph: dies too easily and takes too long to come in play to be a great threat.. price of 50 was great.
Poison: used by most team to come as a great surprise threat and is really effective... worth 100-110 easily!
Armagio: barely worth playing... not worth more then 30.
Gravity pull: works really well with titans/dolls and can be helpful at other times too, it is worth more then 60... would have picked 80 but 70 is an ok middle ground.
Catapult: Useless outside of catatitans and not that great even then... not worth more then 40-50.
Shard of intergrity: been discussed before... wouldn't used it even at a cost of 30 because of the 50% rule (even at 40% if the role comes back) and becuase of the insane price of combined shards!
Emerald dragon: 60 is a bit high as it rarely wins by itself anything... 50 is enough.
Druidic staff... 60 is a bit high as it rarely pulls you a win even when flying them... 40 is enough.
Forest spirit: great filler for nova deck, worth at least 80... maybe 90.
Firebolt: a great cc and is the main weapon in many stalls as it can 1hk... it is worth well 110 if not 120.
Trident: up there when we talk of the lamest weapon for an element... not worth more then 30-40.
Steam machine: Too slow to be effective, not worth more then 30.
Miracle: good card, but not worth 150.. sancurary will be much more helpful then miracle to save you.. and they are 130.... 110 would be enough
Dragon fly: key card in air rush.. worth it's 50!
Procrastination: one of the lamest shields, not worth more then 30-40.
Ghost of the past: nice in rush, and the master card in ghostmare.... totally worth 80-90 cards!
Black dragon: meshes really well in many dark decks mono/pu+ls mostly but a great filler in most dark deck too... worth at least 80.
Devourer: the card everyone hates and face to see... kills all the off mark deck and anything that is not high on quanta... worth 100 easily!
Vampire: really useful in devtals and in monos with eclipse... worth at least 50 if not 60.
Voodoo dolls: great to be poisoned but mostly to receive gp on it... there was 0 need to put the price down! Worth 60.
Nightmare: great fractal killer! Absolutely needed in ghostmare (duh!), great in monos and in nova decks... worth at least 120!
Cloak: .... not a great card, but better then a 10 cost.... should look more like 30.
Lobotomizer... the actual price is a bit high 50 would be more accurate as it is mostly a filler for aether only.
And that's it!!
