@Hellish hell then nope I haven't

A few times, usually a double of the same rate-up servant:

Summer BB x2

Edmond Dantes x2

I also got Prillya and Da Vinci in my first GSSR roll

And I think I got Osakabae and Kama together in one 10-roll

Jigoku-san:

Can't remember a time... (╥﹏╥)

Birdie, I thought older players would have had at least one roll like that.

I got a double Britomart, a double Kama Assassin and a double Musashi Saber (all of them will be my Grand Servants). And I once got a triple in a gssr.

Destiny order spook

@Empty0414 Too bad no Archer Emiya and Gilgamesh for the Extra crew :P

Yes, but very rarely.

I got 2 Yang Guifeis in one 10-roll when she came out on New Years banner.

And if I remember correctly, I also got 2 Summer Melusines in one 10-roll as well.

Unfortunately, those were the units that I didn't actually want.

Jigoku-san:

Unfortunately, birdie's lucky feathers have only been falling. (╯︵╰,)

A few times. On a split rate banner for Tamamo and Beni Enma I got both same multi. I got Arjuna and Illya same multi when it was the last copy to get NP5 so I thought I may have gotten my first USO, but I dodged it. Last time I got 2 in one multi I posted about on here, double Odysseus spook on Tiamat summer's banner in one roll. Outside of that I can't quite recall any others if they happened.

Quick edit: Oh right I got double gssr rolls a couple times. Phantasmoon and someone else, Super Orion + Castoria are the ones I can remember.
