Does this card still need to be limited really? There's far more powerful cards in the game now, it's been power-crept a bit as plenty of cards have protection against it.
*looks at card description* yeah I mean I don't know what Konami thinks when they make cards.
I hate this card it looks almost like a rat
Not gonna b limited
Deck is a bit bricky and banishing your core is quite a heavy cost.

That being said... IF THEY DIDN'T LIMIT SAMURAI SKULL, they won't limit Maximus.

So today i was fighting the Vagabond and he pulled more than 1 Maximus... is the CPU not affected by the limited card restriction?

PS = The vagabond uses real people's decks so i checked his deck post battle and i saw 3 Maximus (despite clearly being limited to 1) and 3 Iron Core... does someone knows if this is plain cheating or does the vagabond not have any rules?

"Excellent Dueling" indeed

Vagabond uses people's Ranked decks from a certain period of time, which depending on the time, may include the days before the banlist hits.

Yeh mine too
Even with the upcoming nerf, this thing is so BS to play against. The whole point of it, and the Koaki deck in general is super rushdown. This thing should only proc its special when its summoned, not once every turn. The deck should not have giant, scary, face-eaters that also maintain board control.

Either make the special proc only when its summoned, or force you to pay some penalty like discarding.

The whole point of Koa'ki deck in general, is Control. That's why they have monsters that disables certain opposing monsters or actions.

Not zerg rush OTK.
Well it’s become abundantly clear that none of you are capable of having a civilized conversation without personally attacking someone in the process (and avoiding talking about the deck entirely). The immaturity here is laughable, but I should’ve expected as much from people who devote so much of their lives and money to a digital children’s card game. This channel is supposed to be about discussing the deck, not randomly attacking those who oppose your opinion.

You did not think it could actually be children who play in the children game?

How unexpected
Big hit on Koaki deck, nice one Konami.
Well I just got a load of these and to be quite frank sick of seeing it, guess I won't be making a Ko'aki deck.

In fact I may as well start making unga bunga decks as everything just gets nerfed into oblivion anyway.

Guess I could use dinos for a month or two.
Maximus is Ultra rare card in a real card game but they made it just R in Duel links..

I think the ban was planned.

It's all Konami's plan. Amazoness Onslaught was once not popular until Konami released Amazoness Princess. GameA rated Maximus as B- , but after Konami released Diamond Core Maximus became one of the most overused card in the ladder. I won't be surprised if Maximus fate would be the same as Onslaught. Hello banlist.

What you mean by doing him dirty?
If it’s not axel my guess is either Adrian Gecko or Jim Cook
Im gonna guess it’s Adrian, but I could be completely wrong
It's not that useful but it's still a 2.5k beater (basically) which is very easy to sum...
