Earthy is the last card to be captured in the first series and it is also the fourth and final elemental card, making it even harder to fight and sense. Since it's the last card that Kero needs to become Keroberos it's also the last card that Yue needs to be born. Sakura's judgement is not far behind...
When the Earthy card is released from its card form, it has the power
to control the earth in any way the caster commands as well as being an
attack card that Sakura could use to fight other clow cards.
