Card Tips:Koa'ki Meiru Guardian
- This card can be searched by "Diamond Core of Koa'ki Meiru", "Koa'ki Meiru Supplier", "Koa'ki Meiru Urnight", "Koa'ki Meiru Boulder", "Iron Core Specimen Lab", "Arsenal Summoner", "Gallant Granite", "Doki Doki", "Reptia Egg", "Aussa the Earth Charmer, Immovable", "BOXer", "Frontline Observer", "Summoner Monk", "Primathmech Alembertian", "Battle Royal Mode - Joining", "Vampire Dragon", "Resonator Engine", "Soul Rope", "Rescue Ferret", "Witch of the Black Forest", and other generic searchers.
- Combo this card with "Neo-Spacian Grand Mole". Not only will you get to use the effect of "Grand Mole" repeatedly, but you can also constantly fill the requirement of needing to reveal a Rock-Type monster each turn.
- Use this card with "Skill Drain", allowing you to negate the effect of an Effect Monster that is not negated by it.
- Consider putting this card in an "Evil HERO" Deck. Not only does it have high ATK, but it can negate any effect monster's effect and be a fusion material for "Evil HERO Dark Gaia". You can reveal "The Dark - Hex-Sealed Fusion", "The Light - Hex-Sealed Fusion", "The Earth - Hex-Sealed Fusion" and even "Big Piece Golem".
- You can force the activation of a mandatory effect, then destroy that monster with "Guardian" (for example, you can attack "Ally of Justice Catastor" and destroy it).
