The Hearthstone Winter Championship is set to kick off next weekend in the Bahamas. From now through the start of the competition fans would be able to choose one from 16 participants and get free card packs depending on their success. Even if your chosen player doesn't get very far, you'll still win one card pack from Mean Streets of Gadgetzan simply for voting.
Additionally, you will receive one additional card pack from the Mean Streets of Gadgetzan each time your champion advances—to the quarterfinals, semi-finals, or finals. If your champion plays in the finals, for example, you would earn four total packs (including your participation pack). All card packs will be delivered to you in-game the week after the Winter Championship.
You can find the full text of the announcement on the Hearthstone site.
