Hello. You can't use an activated power (that which require exhausting) of an ally that was played on your last turn, during your opponent's next turn. Rule 701.3 talks about that: An activated power is a payment power with an activate ( exhaust / "tap" ) symbol as part of its cost. To pay that part...

I would say "Yes" to both your questions. Since Arcane Enlightenment doesn't say "Remove it from the game after you play it." (or something like that) I think those abilities go to the graveyard again, so you can "re-cast" them infinitely. If a non-ongoing ability resolves, it goes to the graveyard,...

No problem. By the way, if you use Discord you can join WoW TCG channel, we talk about rules there also.

There aren't too many players on this TCGBrowser forums unfortunately.

Yes you can, because Untargetable is a keyword that works only while the card (ally in this case) is in play. Untargetable : A keyword power that cards can have. It means “This card can’t be targeted.” Such cards are untargetable only while in play. An untargetable card in play can’t be chosen as a ...

Anti-Magic Shell doesn't target anything, it just prevents the next non-melee damage. What ally in a graveyard you have in mind?

Hello. Yes, you can also prevent combat damage dealt by allies with non-melee attack type. Anti-Magic Shell doesn't specify if this have to be combat or non-combat damage, so you can prevent both.

Yeah, seems like it was just a "future proofing" for some new potential interactions, which finally never landed in the game.

EDIT: It's confirmed by a judge on WoW TCG Discord channel.

Hello Aggro . Well, there's no such thing as multiple attackers as far as I know, so I'm not sure why there's "attackers" printed on Blink (but I'll try to investigate on that topic, I'll let you know). But it just means to remove a character that is attacking your hero from combat. And only that co...

Hello. If you want to play online with your own deck I know that there's an active group of people who play constructed (and raids) via Tabletop Simulator. You can see more info here: http://steamcommunity.com/groups/wowtcg Discord is probably the best way to contact them directly and arrange some p...

No, I don't think Khadgar can lower the cost of "X" abilities. They are treated as 0 cost cards until you play them for a chosen value.
