Mechborn is a rare case of character that has two abilities. Would it prioritize his first ability over his second one?
I believe it still asks you which one to activate. Feel free to test that if you have him.
I don't have Mechborn. The AI does though, and I do have some Undead Corruption
. Nope. It defaults to thinking you want to use his ability to buff himself. I even tested this with 12 resources to see if it'd use his second ability after using his first. To be fair though, he's one of few cards that has a second ability and you're more likely to want to buff him than Evolve him early on. Considering we've had to deal with individually clicking to activate abilities up to this point, one card is one card, and generally most cards only have one activated ability.
Also, Recurring Nightmare can't just be right-clicked to play, but he's in the graveyard and it's not technically an ability.
On another note and a suggestions, perhaps right-click could be more featured? Example: You know what an ability does, so you right-click to play from hand. You have a character? Right-click plays it to default zone. So most go to support, Charge goes to assault and Vigilance goes to defense. In the case of haste, simply clicking Play Card would put it in support un-exhausted, so do that. Just a suggestion, but I'm sure there are some people who wouldn't mind not having to manually drag everything.
