Add 1 "Koa'ki Meiru" card from your Deck to your hand, except "Diamond Core of Koa'ki Meiru". You can banish this card from your Graveyard; for the rest of this turn, "Koa'ki Meiru" monsters you control cannot be destroyed.
When Koa’ki Meiru Crusader destroys a monster by battle he can retrieve a Koa’ki Meiru card from your graveyard. Use this to retrieve Diamond Core of Koa’ki Meiru for more searches.
Iron Core of Koa’ki Meiru
Iron Core of Koa’ki Meiru is the key card of many Koa’ki Meiru decks so search it out with Diamond Core of Koa’ki Meiru. And with Iron Core of Koa’ki Meiru in your hand you will have access to support like Iron Core Luster and Iron Core Specimen Lab.
All GY effect that doesn't have the clause "(Quick effect)" or "during either player turn..." can only be activated during your main phase. Only trap's GY effect (like U.A. Penalty box) can be activated anytime.
Its not chaining towards treacherous , but rather active right after treacherous resolves. Thats also a reason neos didnt get destroyed after being struck by divine wrath, in spite of being a counter trap. He still get his eff negated tho. This is he same case with neos fusion protection eff.
BTw in case of enemy turn, you should notice neos fusion and this card has a huge difference. Neos fusion protection is being actived in RESPONSE to neos destruction, meanwhile this card has to be actived manually beforewards. It is not responding to anything, which mean you cant use it during ur opp turn.
You can't ruin something that, by its very definition, is broken. Anything that can shake things up even for a little while is always welcome, unless you're satisfied dueling against the same 3 or 4 decks in PvP that is.
Koa'ki Meiru are actually stronger now thanks to 3 Iron Cores.
Btw, they are going to limit diamond because Koa'ki Meiru ALREADY topped competitions such as the KC CUP and the WCS. It's an archetype that already had its time to shine, it's been meta for more than 5 months.
That's the point, it acts as an additional safety net for your Koa'ki Meiru monsters.
I love the game and have been playing for many years, but this deck as it is and with all the restrictions they applied to it,simply put has rendered it an into garbage an almost unusable and handicapped disaster.
Bcus the box is old enough to have served its purpose, and with Neos-Koaki dominating the championship season they had to hit the deck someway- and since they won’t hit Neos Fusion they had to hit Diamond Core
