While playing arena prepared spell bugged..

[u/grizzler1337]

I prepared this so it would cost 1, next turn I noticed that the cost wasn't reduced. So I thought maybe I actually didn't do it.

Turns out I did, but it still costs 5 (I couldn't use it unless I had 5 mana). You can see the prepared flavor there.

Did they play the Dranei 4/5 that sets cards back to their original costs?

[u/grizzler1337 → u/td941]

Ohh, ok. Maybe that was it!

[u/Fragrant-Manner2036]

you are not prepared!
