The Battle Gem monsters (バトルジェムモンスター Batoru Jemu Monsutā) are a new mechanic of monsters first appearing in LHK's card, "Precious Knight". They gain effects only when battling (hence they have beatsticky-like ATK) and specific effects depending on the rarity of the attack target.
Note is that if the attack target is a Common, Starfoil Rare, Mosaic Rare or Shatterfoil Rare, they gain the same effects regardless of the difference of their rarities themselves.
Rulings[]
- If a Battle Gem monster you control has an effect that activates when battling with an Ultra Rare monster (for example), and it battles an Ultra Rare variation of a rarity (for example, Duel Terminal Ultra Parallel Rare or Millennium Ultra Rare), that monster can activate its effects as if it battled an Ultra Rare monster.
- If a Battle Gem monster you control has an effect that activates when battling with a Millennium Rare monster (for example), and it battles a Millennium Ultra Rare monster, that monster can activate its effects as if it battled an Millennium Rare monster.
