I don't know if all Rescue cards will have abilities, but in the beginning they surely will, it's a whole new clan and they need those ability to balance out with all the other favorite clans. Ok it is true though that ever since august every new card (not just from the new clans) had an ability. There were no ability-less cards but for the Rescue clan this is normal (metagame and stuff). Most clans have between 3 and 5 cards without an ability, so have no fear there probably will be Rescue cards without an ability not just yet though.
Oh yeah Hax at lvl 4:
7 power 3 damage Ability at lvl 5
I really like the Rescue clan they are an answer to all the pill eating decks that are out there and always consist of the same type of cards. But one thing I don't understand is the pricing players give the new cards in the market. Steve being a rare 2 star card costed more than 30.000 while actually the card isn't worth anything in the game itsself (he's just a bad 2 star copy of slyde) but he started out more then any cards I have seen weeks. How do you guys pick these prices for cards? You just look at rare, uncommon or common, or do we actually take in mind the use of the card in the game , when calculating market prices
It's a "free market" and that's simply the way it reacts, when new cards are introduced everybody wants to have them, there are only a few to go around and the demand is big, also there are players who buy the cheapest ones in order to sell them for a little more.
Many players actually don't even have the time to evolve them before they sell so they really don't know if the cards worth anything in the game, so I guess they just put the bigger price on the rare cards that maybe are the most powerfull ones.
All this translates into high prices in the first few days then they slowly reduce and when the new batch of cards arrives, when players stard to buy again many packs especially new blood, the prices of the previous cards achieve really low points.
So if you don't really like the prohibitive prices of the new cards in the first week just wait untill the new batch arrives and buy the previous cards.
