"(Gem) 20,200 wildcard value!"
The Japanese version of this sales pitch means "the equivalent of 20,200 wildcards."

This is an impossible value for users familiar with Arena, and while it's possible to assume that it's the value of gems,
the current situation clearly leads to a significant misrepresentation of value.
Under Japanese law, this is referred to as "Yu-Riyo-Go-ni-n (misrepresentation of quality)" and is subject to administrative sanctions.
