EDIT: Revised the cards, tried to make them more playable.

NOTE: I know "Savior" isn't a type, it's supposed to be like the Spirit sub-type used with Yata and such.

1 savior ain't a type thus they are useless

It's a sub-type, like Spirit for Yata and Tsuku. Besides, it's not like these are real cards, so who's to say that I can't create cards with made up sub-types?

I know I'm being picky, but could you put them in the regular format please? That makes them easier to read. If you don't know what I mean, check out either Chaos Command Magician's topic or my topic.

And also, a lot of your effects seem to be too powerful. maybe you could lower the ATK and DEF on some of them to make it fair, or at least make the effects cost more.

Thanks for the input. I'll keep that in mind when I create the rest of them.
