I see what you did there,...

adding those two Gudaguda berserkers. Those would be great actually and Lavinia.

Rama and his Sita are separated forever. Sita is in the Arcade, but Rama is not in it. And in the mobile version, there is Rama, but no Sita. Therefore, I find it pointless to add Sita.

I choose to kick logic to the curb and do the impossible!

Shirou is already a servant as an Archer.

Here,they probably mean Shirou as a master, not a servant.

@Mega gk masters don't get summoned, servants do. Shirou did a lot to be in the Throne of Heroes, after his deal with the Greater Will.

Demi-Servants and Pseudo-Servants are different. Pseudo-Servants just use the human they possess sometimes with the human having some control.

We have a Master from Fate/Samurai Remnant as a Servant, so we could have Shirou as a Servant. Besides, I didn't make this tier list, so I have no idea why Shirou and Shinji are here.

Atp, can't we just summon regular humans as servants, like Shirou?

The Mahoyo trio pretty much showed up by themselves, no body possession.

I think there's always room for FSN Shirou to join at some point.

@Muhammad Abdul Aziz Habibi I don't forget Lady Kasuga, I wish she was the Lancer Class Servant or costume dress for Parvati.

Mahoyo characters are the way they are because they're pulled from 'end' of Mahoyo.

Aoko's Foreigner class was speculated to be indication she'll be survivor of the series (alongside Tohko), as Nasu didn't deny Soujurou's NP is based on his final moment on future Mahoyo chapter.

Iori is similar. His playable FGO ver. is based on Sam-Rem route where he died.

So its not like they pulled everyone, saying 'screw rules', it works because TM knew Mahoyo characters, Iori and Yui do met requirements to be summoned in future.

Pulling Shirou from FSN is tough work because every route where he died always he died before reaching his full potential. If he fully realized his potential before he died, then its one-way trip to EMIYA. So do if you wanted Rin and Sakura from FSN thus pseudos for them. Your best bet are Shirou, Rin and Sakura from Prisma Illya.
