I don't spend a lot of money on this game. So far I'm at $15 in the last year. With that being said, earning enough Tokens, Nixon coins, Giggitywatts, and Gems can be difficult, and a lengthy process if you're still trying get higher up on the leaderboard to earn some really cool prizes and packs. I'm saying all this because we may have some newer players every now and then that might be trying to just work at deck building and resource collecting.
There are two (2) daily rewards that can help you retain giggitywatts while fulling the requirements and earning 1000 Nixons. The first daily reward you want to complete is the buy 3 packs. Spend 300 Nixons on the basic pack, and you'll get back 500 as a quest reward.
Next upgrade 3 common cards once each for a total cost of 6 giggitywatts. You'll receive 500 Nixons as a quest completion reward, and when you recycle those cards you'll get all 6 giggitywatts back as a recycle reward.
The outcome is 2000 Nixons spent on 3 packs, and zero giggitywatts spent on upgrades.
