United in Stormwind Cards List & Guide
I just want to know what the best cards you have gotten from unstable portal. I just played a game where I had both in my starting hand and got ysera and then king krush.
Mistakes were made
I got an owl from one of them, which was pretty crap until my opponent played a Twilight Drake next turn.
coined out unstable portal and got Lord jaraxxus on turn 1
Unstable portal'd Onyxia, Tirion at turn 5!, Deathwing and Mogor which resulted wins in Arena.
