Card Tips:Koa'ki Meiru Sandman
- 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", "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.
- If your opponent has face-down cards while you have a "Koa'ki Meiru Urnight" on the field, and you are wary about attacking, use the effect of "Urnight" and Special Summon this card. You can then attack in relative safety, with this card preventing the use of your opponents' Traps.
- You can reveal "Koa'ki Meiru Boulder", "Koa'ki Meiru Guardian", "Koa'ki Meiru Wall", "Koa'ki Meiru Prototype" or another copy of "Sandman" to pay for this card's Maintenance Cost.
- If "Dimensional Fissure", "Macro Cosmos" or any other card that would banish this card is used, then you can use "Release from Stone" or "D.D.R. - Different Dimension Reincarnation" to reuse this card's effect.
- When your opponent activates cards like "Bottomless Trap Hole" or "Dimensional Prison", don't forget that, even if you can't save your monster, you can choose to send this card to the Graveyard instead of banishing, for later reusing it with "Core Reinforcement".
