I just played a Tomb Spider in Arena and one of the choices was a Volcanosaur :> Is this intentional that this card is in the game now because of the loggin reward, or just a bug?
Well, I did try it in standard now and for some reason, poisionous adaptation did nothing for me (attacked into 6/6 and it survived with 1hp). Am I the only one, or is it a global bug?
That is a bug, a minion with poisonous should always kill any other minion it damages. Jesus I hope blizzard don't screw up and let any bugs pass through the patch.

No, it's intentional. The card is now available in Standard, so it's also available in the Arena
It's available in standard now?
yepp, you could even draft it in your next arena run.
