Opened only one pack today and snagged a legendary!

I literally only bought one pack today to open and did so with no potions even to help with the pack opening. To my surprise I managed to snag a legendary Torrent Fiend, the 0 mana cost legendary for the Water splinter.

This is probably the best luck I've ever had on a one pack purchase before.

Don't want to press my luck and buy more now but I'm thrilled to have pulled this when often times the packs don't return what you paid for them initially.

Solid day today though!
