Pity that the names need to be this way around for the colours to be consistently ordered.

I like the names and their ties to the effect. A sorcery-speed Orim's Chant is fine. A one-sided Void is pretty strong, but the play is interesting enough that I'm fine with it.

I can't help feeling that on each of these three split cards, the black half is much better than the white half. (The black half is removal in 2 cases, whereas the white halves only approach card advantage if a 1/1 flyer and a Plains counts.)

Isn't judge/Orims effectively Timewalk in white, and not significantly upcosted? Youch!

I always did like the Kirin ability to kill numbered stuff; seeing it in black as a one-off makes sense. It's kinda very very good though because it's only affecting one player. maybe to address the power concern it should be "all players"?

But yow, Orims just sems incredibly broken to me.

The key difference between Orim's Chant and Time Walk is that the opponent still gets to draw their card and play their land. So you're getting card disadvantage, and nowhere near as much tempo advantage as a true timewalk. Once you factor in the two mana to cast your spell (or three in this case), it's fine.

(Orim's Chant does in fact turn out to be broken, but not for the reason you think; instead because it can be put on an Isochron Scepter.)

Re: black side stronger than white It does seem unbalanced. Maybe move some effects onto entirely new cards. Replace the black side with cheaper effects. Executioner would stay. I have a neat idea for Under.

judging by DGM splits, they might have reordered the colors of the splits. as such i will order them by the phrase rather than by color. so judge will be on the left side.
