Fang Zheng's confidence wasn't without reason. Generally speaking, there are several ways to do card draws in mobile games, with the most common being single draws and ten-packs, and perhaps even friendship draws. But beyond that, there's a situation that designers must take into account.
After all, in mobile games, top-ups rule. But the problem is that the controlled probability in mobile games is limited. You can't guarantee that every top-up tycoon will be able to escape Africa and enter Europe. What if someone is born with an African aura, and no matter how much they draw, they can't get the card they want? What then? Could you really afford to drive away a top-up tycoon who's finally willing to spend money?
Of course, that's impossible. But what if the tycoon doesn't get a five-star and doesn't want to play anymore?
That's when a new way to top-up emerges.
That is... Special Summon!
