The “Koa'ki Meiru” archetype revolves around Iron Core of Koa'ki Meiru; the vast majority of the monsters self-destruct during the End Phase unless you send this Spell Card to the Graveyard or reveal a certain type of card from your hand.
Revolution Beginning, the 17th Main BOX, has finally given us, together with some of the monsters we were still missing, one of the best support cards this archetype has ever seen: Diamond Core of Koa'ki Meiru. Koa'ki Meiru decks are now significantly more consistent and, as a direct result, more threatening.

Use Diamond Core to add Iron Core of Koa'ki Meiru, Koa'ki Meiru Urnight or Koa'ki Meiru Maximus from your Deck to your hand. You can’t add another Diamond Core to your hand, but there is no restriction on how many you can activate in a turn.
If all of this wasn’t enough, you can banish Diamond Core from your Graveyard to prevent all “Koa'ki Meiru” monsters you control from being destroyed this turn. You can activate this effect the same turn you activated Diamond Core and make your monsters immune to cards like Treacherous Trap Hole, Widespread Ruin and Super Rush Headlong.
Since your monsters can’t be destroyed by battle this turn, you can also safely attack monsters with the same ATK with them. Most of the times you do not want to add Koa'ki Meiru Sandman to your hand with Diamond Core because Koa'ki Meiru Urnight can Special Summon it from your Deck.
As I said in the Overview, the “Koa'ki Meiru” archetype revolves around a card in particular: Iron Core of Koa'ki Meiru. Iron Core can be recycled from the Graveyard via its effect, so, even if a monster requires you to discard it, you are not going to run out of them, but the case is different with Koa'ki Meiru Maximus because this Level 8 monster can only be Special Summoned by banishing the Spell Card.
If Iron Core is banished, there aren’t many ways to retrieve it consistently. In addition to requiring you to banish Iron Core in order to be Summoned, Maximus doesn’t just ask you to reveal a card during the End Phase: you will have to discard a copy of Iron Core or a “Koa'ki Meiru” monster, otherwise it will destroy itself during the End Phase.
This deck is built to make explosive, aggressive plays, so it generally doesn’t care about maintaining this monster, but, thanks to Diamond Core, you don’t necessarily have to discard anything during the End Phase.
Once per turn, Koa'ki Meiru Maximus allows you to destroy a card your opponent controls. You can destroy a Set Spell/Trap Card or a monster and, if you have more than one Maximus on the field, you can use this effect with both of them.
Maximus alone isn’t enough to deal with everything your opponent has on the field and, even though it does have a lot of ATK, it’s not going to be enough for an OTK.
Once per turn, Koa'ki Meiru Urnight can Special Summon a Level 4 or lower “Koa'ki Meiru” monster from your Deck, except another Koa'ki Meiru Urnight, if you reveal an Iron Core from your hand. Use Koa'ki Meiru Urnight’s effect to Special Summon Sandman and then Special Summon Koa'ki Meiru Maximus. Now you have a board full of monsters, Maximus’ destruction effect and Sandman’s negation for a Trap Card.
