No you cannot find the holiday MAG cells offline.
:'( *Sob*
EVIL!! :evil: ROOOOOAAAAAAAARRRRRRRR!
I can't ever get anything that's cool. *gets in fetal position*
That's SEGA's strategy for you! In PSU especially, of course the online play is more packed with stuffers than offline! Offline is fun though, so enjoy the adorable MAGs!
. . . . . . . . . adorable. I cna't find my one
true mag. I need one for my guy.
awwwwww. My sato is the only one who understands me. CUMMON TELL THEM!
Sato: . . .
Yes, yes. I see.
He says if I get another black sato, he will not let my FOmar survive.

Indeed, it has always been ST's style to cheat players out of their money each month by not releasing their promised content on time -or ever. Take my advice, seek out new servers; don't waste your money on ST.
STINKING HUMANNNNNNNSSSSSSSSSSSSS!
I need to get it. . . but I don't want to be cheated out of $$. Why?
I MADE UP MY MIND! I shall make ANOTHER sato or deva and suck it up and allow everyone to have a good life! Which one is better for an android?
Since you're offline... likely Deva since it actually gets you some Shifta and Deband... but if you have the Shifta and Deband Photon Blast... then either works just fine. XD
Why not go for a Nidra there cute and reliable plus they'll poison you if you don't feed them....kidding there alright.

Nidra's are gross looking... it's as simple as that. XD
There not gross, there very adoreable with there little pincers and that stinger. It just screams cute or maybe that's it's battlecry.
