So with new cards being introduced in the basic and classic set, lets discuss their impact on arena. Most of them seem at least playable, some of them quite strong. The fact that they will be in arena every rotation, since they are part of the core sets, is important as well.
Let me share my first thoughts after seeing these beauties :)
Rating (1=excellent, 2=good, 3=average, 4=poor, 5=terrible)
Plaguebringer (1): Plague Scientist was a pretty ok arena card, but never an exceptional one due to the combo activation. This will be much better, since it is a battlecry. Stats r not that bad considering the effect, but you will have to be at least on board to take advantage of it. It will definitely be a heavy snowball card, that is for sure.
Radiance (5): Priest got the shortest of sticks here. I dont think anything can save this card in arena, i would probably rather have Purify than this and Purify was removed from the drafting pool back in a day for how bad it was. Just no :D
Siegebreaker (1): This card will be pretty strong in warlock. It is not the best 7 mana taunt we've ever seen, but the demon tag and the potential Raid Leader ability for demons might more than make up for that. In general, warlock does not have consistent access to strong taunts and this is a good one. And the potential demon synergy that will always be there, since Classic set is a core set and does not rotate, needs to be kept in mind.
Gift of the Wild (1): This card will be Silver Sword level broken, mark my words. Yes, it is coslty AF and you probably dont want more than 1 (max 2) copies of it in your deck, but you want it in your deck. Everyfin is Awesome was being played for 7 mana back in a day and it was a powerful buff card. Druid with its swarmy style, where you want to be wide on the board most of the time, will love this card. Not only can it act as a finisher (expensive Savage Roar), but more importantly, it can be used pro-actively, buffing your minions out of AOE range or help them trade up, survive the trade and/or push some more face damage all in the same turn depending on how you need to distribute your attacks. This card will make an impact.
Righteousness (3): We knew this card was coming sooner or later, it was just logical. I personally was curious what cost would it end up having and i think 5 mana is fair overall. It might be hard(er) to get decent value out of it in arena, but it can be a powerful win more card. Free trades into enemy minions or a pro-active protection from aoes? Even if (when) it lands on small minions, it will be SO annoying to get rid of them, cause you will have to spend more resources than you would like to, leaving minions up for paladin is always asking for trouble.
Brightwing (2): Decent value generator. It is no Messenger Raven, but close enough.
High Inquisitor Whitemane (1): Another super powerful win more card. You kinda need to be on board to get full advantage of it and you need to be able to trade the minions off, which is not what you usually want to do, but you can get an insane swing turn with this, literally Kel'Thuzad for 1 less mana that will trigger once. Often times might just win you the game on the spot. The base stats are actually good enough to play this card naked, so literally any minion you get from the battlecry makes this insanely powerful.
Barrens Stablehand (3): Little bit too RNG for my taste, but looks like an ok card on average. I can already see the trollden King Krush lethals from nowhere.
SI:7 Infiltrator (3): Very good card. Nothing amazing, but very nice card to have in the mix. Decent stats and nice ability to squash those secret lovers.
Arcane Devourer (5): I dont think we will see this card very often in arena. Maybe when you get it via random effect and you are so far ahead (or so far behind) that you will eventually play this. But 8 mana is just damn too high to combo it with anything on the turn you play it, not to mention that spells are kinda sparse in arena overall.
So, there you have it! Obviously a big portion of power level of each card will also depend on the power bucket placement, if they are placed properly, you might not see many of them too often, cause other as powerul (or more) and/or more versatile cards might be picked over them, but most of the new cards seem to have a strong potential in arena. Only time will tell :)
