A Kiwi and an Aussie are two of the 16 Hearthstone players vying for a piece of a US$250k prize pool in Shanghai this weekend.

Australia's Paul "CitizenNappa" Yang and New Zealand's Ki Yin "Mage" So are the local hopefuls in China for Blizzard's Spring Championship, which is part of the 2017 Hearthstone Championship Tour.

Alongside the substantial prize pool, four seats at the Hearthstone World Championship are up for grabs.

The tournament will run in a Conquest format – best-of-five matches with one ban – so each player must bring four different classes in total.

Initially, four players – one from every region – are seeded into four groups. After the dual tournament group stage concludes, the top two players from each advance to the single elimination playoff bracket.

Last month, "Mage" won the Asia-Pacific leg of the 2017 Hearthstone Championship Tour Spring Preliminary, and "CitizenNappa" placed 3rd/4th.

There will be a Hearthstone expansion announcement made at the tournament on Friday July 7 at 12:00 PM AEST / 2:00 PM NZST on the official Hearthstone Twitch channel.
