Zatara family vs. Rasputina family

Zatanna, Zachary and John Zatara

VS

Magik, Mikhail Rasputin and Colossus

does it make a difference whether Piotr join or not ?

Yes. As Colossus has a high end resistance to magical effects on his armored form, and can effect magic more easily than others.

hm...
what I want to know is which can win
and if Rasputins take this, whether the two need Colossus ?

They don't need Colossus
Illyana and Mikhail are powerful enough

What were some of Mikhail's best feats?

I know Magik has owned beings like Dormammu.
