Thankfully, Blizzard provides the possibility to purchase Battlegrounds perks with in-game gold instead of real money. The pricing is impressive, though – you’ll have to spend 2 500 gold, which isn’t a sum that you can easily obtain. To gain the in-game currency quickly, play every day, especially top-tier decks, and re-complete daily quests. If you’re skilled enough, play in the Arena mode. Don’t forget to keep an eye on the new event updates – usually, the gold earned during events is doubled.
