The number of beasts that REALLY like this card will determine how good it is. And right now, although it's not a huge number, it is enough for it to possibly see play.
I can only see this being played in face Hunter because a two mana deal five to face is appealing, but this card will only do so if there is room over the other two drops in the deck (and yes, I'm considering HP on two after Toxic Reinforcements as a better two drop than this guy).
New Neutral Minion - Scavenging Shivarra
Not the best since it has low health and potential to hit friendly minions. Perhaps it'll be a nice card to get back the board in arena.
New Neutral Minion - Dragonmaw Sky Stalker
Solid stats, but not much Dragon synergy in standard. Perhaps it'll see some usage in wild.
New Shaman Minion - Lady Vashj
Kickass art imo. Its so awesome to see all these Frozen Throne/Burning Crusade "heroes" making a comeback.
New Neutral Minion - Bonechewer Vanguard
An interesting arena card, but doubt it'll see much use elsewhere.
New Neutral Minion - Supreme Abyssal
Only good if silenced or taunted, really.
New Neutral Minion - Infectious Sporeling
Very strong removal effect, and unique as well. Very curious to test this one.
New Neutral Minion - Blistering Rot
Only useful if it can be buffed, so not the greatest of cards.
New Shaman Spell - Serpentshrine Portal
Liked the portal mechanic so this is welcome. Seems like a strong card which will be in most Shaman decks the next couple of years.
New Neutral Minion - Scrapyard Colossus
Strong arena card, doubt it'll see much use in constructed though.
New Neutral Minion - Mo'arg Artificer
This one has crazy potential, specially in the hands of a Mage.
New Neutral Minion - Replicat-o-tron
With the mech synergy going away from Standard, it'll likely shine in Wild where it can take advantage of multiple buffs.
New Hunter Spell - Pack Tactics
Just a pretty good card. Even as a two mana 3/3 vanilla because, being a secret, it can force your opponent to play suboptimally.
New Neutral Minion - Waste Warden
Very versatile card, will likely be amazing in arena.
New Neutral Minion - Teron Gorefiend
Seems rather risky, but will likely shine in Wild with cards like Baron Rivendare.
New Neutral Minion - Maiev Shadowsong
Possibly a must include in every midrage or control deck, as it's a great way to remove a target from play and still have decent stats on the board.
New Neutral Minion - Magtheridon
Seems very strong in theory. Perhaps Demon Hunter with Immolation Aura and Bloodmage Thalnos can make it work consistently.
New Neutral Minion - Al'ar
Not the strongest, but can become a recurring threat if left unchecked by the opponent.
New Neutral Minion - Kael'thas Sunstrider
Loving this card, makes for some very sick combo potential!
New Hunter Spell - Scavenger's Ingenuity
The number of beasts that REALLY like this card will determine how good it is. And right now, although it's not a huge number, it is enough for it to possibly see play.
New Warrior Minion - Imprisoned Gan'arg
Decent if played early on, not the strongest though.
New Warrior Spell - Sword and Board
Not the strongest of cards, doubt it'll see much play.
New Warrior Minion - Bonechewer Raider
Strong card if the battlecry can be used early on.
Let's create a Shaman Imprisoned Demon - Challenge?
I submitted this for the WCDC this week. Also, Rogue has none too.
New Warrior Spell - Corsair Cache
Great potential if played in decks with weapon synergies, such as pirate Warrior.
New Hunter Minion - Imprisoned Felmaw
I can only see this being played in face Hunter because a two mana deal five to face is appealing, but this card will only do so if there is room over the other two drops in the deck (and yes, I'm considering HP on two after Toxic Reinforcements as a better two drop than this guy).
