So I've been watching (and playing) a lot of Hearthstone recently. Amaz is one of the top Hearthstone streamers. He plays a lot of international tournaments and is sponsored and stuff.
The NA server was down today so he went over to the Asian server to play, where he's really lowly ranked (rank 25, the lowest you can be). He has a really good deck (really rare and powerful cards) because it's like LoL, where all the top players play on different servers to get different experiences and I think he farmed up these cards.
Anyway, he goes over to the other server to play and plays against another rank 25 who only has all the basic cards (basically, the free cards that you get at the start of the game).
And then he loses!!! LOL.
It would be like if a Challenger level player in NA went over to another server and lost a 1v1 versus a Bronze.
