Title says it all, on the post game awards screen I got the card "Ash" (the thing a dead phoenix turns into) as my reward.
I am pretty sure it was against a 1hp deck that I beat quickly, so it wasn't even like they could have shuffled an ash on board into their deck to explain this somehow, so I'm really not sure how this happened.
Pictures included as proof, as well as a bit of some context from the blab chat where I mentioned this.
Things I've already tried / results:
relogging - it's still there
putting it into a deck - it let me
putting it into a deck with 6 phoenixes - it let me
playing against level1 ai with ash in the deck - it worked (and I drew and played ashe for 7 mana as expected)
tried to queue into pvp with someone from blab chat, it seems the game does recognize that my deck is not valid and won't match me with someone while I have ash in my deck (tried multiple times and every time I took ash out and replaced it with phoenix it instantly let me find a match, both pvp1 and 2)
tried to play the pvp duel (no rewards) and it let me play with someone from chat using, drawing, and playing ash
I haven't tried (and dont plan to) putting it into an arena deck, but given that's how I found it, I'll assume that works too.

[04:18:21] ‹nighthawk475› I just got "Ash" the card, as a reward from arena?
[04:18:34] ‹nighthawk475› the thing phoenixes turn into...
..
[04:18:38] ‹dawn_to_dusk› Pics or it didn't happen
[04:18:55] ‹nighthawk475› [**redacted link** see above spoiler]
[04:19:02] ‹DoctorC› ‹@nighthawk475› That's impossible, isn't it? o.o
[04:19:09] ‹nighthawk475› two monitors, pay attention to right half only
[04:19:11] ‹nighthawk475› it should be @.@
..
[04:19:25] ‹nighthawk475› I'll put it in a deck and see what happens, lol

[04:20:13] ‹nighthawk475› followup: [**redacted link** see above spoiler]
[04:20:14] ‹DoctorC› ‹@nighthawk475› What kind of sorcery is that? O.O
[04:20:15] ‹nighthawk475› it worked
..
[04:20:42] ‹nighthawk475› queued into l1 ai so I could back out to menu and replay until I found it in my opening hand
[04:20:55] ‹nighthawk475› wtf
[04:23:00] ‹DoctorC› Wait. If you got Ash from someone in the Arena, then that means that this someone had Ash card too...
[04:23:14] ‹DoctorC› That's creepy.
On the bright side - at least since it costs 7 to play there's almost no gain from putting ash into a deck by itself, so this shouldn't affect balance/gameplay if it becomes more widespread... (I'm tempted to try upgrading it, but I have better things to waste 1500g on atm)
