RD/KP17-JP010 ダイスキー・メクル Dicekey Mekuru
Level 1 LIGHT Fairy Effect Monster
ATK 100
DEF 100
[REQUIREMENT] Send 1 card from the hand to the GY.
[EFFECT] Excavate the top 6 cards of your Deck and reveal them. You can choose 1 “Dicekey Ribbon” or 1 LIGHT monster with an effect that rolls a six-sided die among them and add it to the hand, then place the remaining cards on the bottom of your Deck in any order.

Note: Mekuru means to ‘flip pages’, ‘turn over’, ‘tear off’. Hence why she’s playing with essentially a sticky note pad esque thing.
