Gem-Knights need a Miracle Fusion that's better than their normal fusion card.

[Greiga]

Miracle Excavation
Normal Spell
Remove from play, from your side of the field or graveyard, fusion materials listed on a "Gem-Knight" fusion monster, and special summon that monster from the extra deck (this special summon is treated as a fusion summon). The special sunmoned monster cannot attack this turn. Once per turn, you can remove from play one "Gem-Knight Fusion" from your hand or graveyard and add this card from your graveyard to your hand. This effect can only be used once per turn.

Better than Miracle without being broken. Konami, print this now.
