Unstable Portal has to be the most ridiculously fun spell in the game. Cannot say how many games it has won for me with its crazy draws. Started playing again last week after some months mainly with mech mage, subbed in Portals and never looked back. Played up to rank 6, don't think i have the time to hit legend though. I just had a ridiculous game against control warrior, which is normally almost an unwinnable matchup, portal gave me a 6-cost Jaraxxus, gg him trying to fight through a horde of 6/6 elementals.
