I have watched the video of B8 (A Dota 2 team) which is sponsored by Stake as the t-shirt of Dendi has the logo of stake and they've got a background of stake too with lighting. It's sad to see this legend's team got eliminated on the qualifiers of Dota 2 in the CIS(Eastern Europe).
The video's aura is sad and I'm sure that the partnership with stake is still going to go on with him and his team. They've been eliminated by Team Unique.
