And second video is opening 3x40 packs (I was looking for specific Legendaries, not getting them I simply acquired more packs until I was able to disenchant for dust to get what I was after):

If you are curious, odds are about 1 Legendary per 40 packs. I got 5 in 120 but I did open about 100 other packs earlier from gold rewards, my first purchase which was $3 just to get gold Legendary Beta Promo, etc, and I kept track of #'s of rarities acquired overall.

Hearthstone: #1 Ranked Player's Supposed Decklist

I am far from pro at Hearthstone at this point, but I did win number of tournaments for Magic The Gathering and honestly these games are very similar to each other. So as I was curious about metagame at top of the ranked play I found decklist posted by Railedlol who Blizzard themselves listed as #1 on list of top 50 ranked players. Perhaps game was different when he got that place, maybe ton of things changed since, but I just don't see this deck doing all that well. He is Australian and apparently tried to have stream, but when I found link to that as well, he does not appear to be streaming at all. Cause stated was 'Australia has bad internet', me living in North America cannot confirm nor deny that.

Here is decklist:
