(When this spirit brave attacks) Discard one card from the top of your opponent's deck. For that battle, your opponent cannot use cards from their hand that have the same color as the card sent to the trash by the effect of this Spirit.
Ruling: If you activate this brave's braved effect first, then activate another milling effect from the braved Spirit (e.g. The Blue Seas WisdomKing), any other colour cards milled by the braved Spirit is counted towards this brave's braved effect.
