I am simply copy/pasting what I submitted to blizzard as a bug-report:
OKAY! No longer than 10-15 minuties ago, I had just reported a thorough in-game Hearthstone bug regarding a phantom-card called 'Mirage; (a card generated by ‘Spirit of the Badlands’) in the bug-report I clearly narrow the scope or domain in which this BUG/GLITCH occurs while leaving the remaining bug-fixing to the staff and/or the support center to appropraitely hand ‘the report’ down the line and on to the path of fixing. After submitting the report, naturally I resume my gameplay aspiring to climb the ladder toward ‘Legendary’ rank. Literally the very next game I play, I find myself in a position to possibly duplicate the scenario/instance of the way in which this BUG occurs. And out of curiosity this is exactly what I do!
I will write/submit this ticket in a similar fashion as the previous one; as it clearly pinpoints down exactly the nature of this bug and how one ought to go about quickly resolving it! I am putting some ‘work’ into this and if any job opportunites exist for a person like me, I’d sure appreciate some information on that (this is fun)
BUG/GLITCH SPECIMAN: [Mirage] - a generated card by the card-subject
CARD SUBJECT: [Spirit of the Badlands]
(2nd and/or duplicated) EXPLANATION OF ENCOUNTER:
Sure enough when playing the ‘mirage’ when it has adopted the form of [Archdruid Naralex] results in the mirage being consumed; from a programming stand-point, the loop argument that reinserts the generated card into the hand (preserving the condition of this card to be unique/permanent fails to function; collapsing the loop argument. This happens either when playing [Archdruid Naralex] specifically and/or any minion that comes into play ‘Dormant’ is my guess. My concern for this begins to grow because my 100% custom secret deck that I take much pride in, also contains another card that comes into play Dormant, that being [Soridormi]. I suggest upon resolving this BUG, one ought to not only investigate [Archdruid Naralex] but all minions that come into play in this way. As you can imagine, I am curious to see if Soridormi would result in the same way but at the cost of possibly throwing the game in a Ranked match? :S
OTHER AREAS OF INTEREST: In my initial bug report I mention a graphical BUG/GLITCH being involved with this as well. In that first report I go on to explain that upon encountering this glitch the ‘layout structure’ and appearance of my hand depicted on oddity where there existed a gap or empty space in my hand where the mirage ought to have been if it was there, this did not affect or jeopardize my handsize, the gap or missing card did eventually correct itself a turn or two later!
BUT this second time, another similar but different graphical GLITCH occurred: the mirage initially looked as though it had returned to my hand after playing Naralex (in this moment for a brief second this really confused me at first). the card was physically there but was non-respsonsive as well as ‘stuck’ as it was layering itelf overtop or under the other cards in my hand. Though the card was not actually there, the game after 1-2 turns did correct itself once again! BUT NONETHELESS, my mirage was gone or consumed again!

ADDITIONAL COMMENT:
a while back (a few months ago) I noticed another oddity regarding cards that come into play DORMANT, this oddity did not strike me as a BUG/GLITCH persay (although it did nerf a little combo I at one time relied on) but in the end after coming to a conclusion upon reflecting on my encounter with the following ‘oddity’, I concluded that the ‘oddity’ was an intentional change or a previous possible bug fix regarding something else that interfered with ‘Dormant’ cards. BUT PERHAPS WHAT I AM ABOUT TO EXPLAIN was unintentional and should still be a thing!:
At one time following the release of ‘Caverns of Time’ but before the release of the ‘Badlands’ expansion. When playing [Soridormi] by the end of the following turn after playing ‘Timewarden’, Soridormi would come into play and gain Divine Shield and Taunt before going Dormant, this was a convenient combo to my deck because when Soridormi would awaken I’d have another line of defense against my opponent (usually a variable my opponents rarely accounted for, often displaying my superiority 
After an unrelated or previous bug-fix, this no longer worked. After discovering this, I was optimistic and hoped that Timewarden would still work on Soridormi but only in the following circumstance: where Soridormi has been dormant for one turn already and when playing Timewarden the turn before Soridormi awakens, perhaps it would proc the Divine Sheild and Taunt, but no, this also resulted in a dud! Leaving me upset with no explanation, but I moved on :).
The nature of Dormant cards are unclear. I am a mathematician and my intuition suggests to me that the’oddity’ I reference here lacks any logic at all, it begs to be reworked. A dormant card may ‘in a way’ be non-existent or not able to interact until awoken, but I still ‘played’ the card from my hand and ‘consumed’ mana to do so. Timewarden should still trigger on Soridormi. Especially when ‘Reno Lone Ranger’ can now wipe anything from the field no question with no restriction to Dormancy? These concepts bump. C’mon BLIZZARD you’re better than this!
