Small Suggestion

Small suggestion: 1. In the late game, you'll be short on game gold. If you're free-to-play, you can log in every hour to get gold. Accumulate a bit more, and you'll have room for error when playing stages (gold can be used to replenish cards or go back a step). I tend to accumulate slowly in the morning and play before work or before bed. With daily login rewards, you actually have quite a bit to play with. 2. Normally, accumulate universal cards, step-back cards, and deck replenishment cards, and save up more gold. When you've accumulated enough, participate in events to play with high multipliers. High multipliers make it easier to accumulate event rewards, and functional cards can increase your margin for error, thus achieving the goal of 'money making money'.
