Depose the Witness
Sorcery
Choose target creature. If you control it, untap it, put a shield counter on it, and until end of turn, whenever you activate one of its activated abilities, copy it and you may choose new targets for the copy. Otherwise, tap it, put a stun counter on it, and it loses all abilities until end of turn.

Witness the Horror
Sorcery (U)
Target player reveals a card at random from their hand. Then, they discard that card unless they pay life equal to its mana value and repeat this process.
You are not the victim, but those that love you. They will remember what you used to be. They will watch you fight, and lose. And you will only wonder at the sadness in their eyes.

Had a heck of a time wording that one and I am worried its still not right.

I'd probably go with something like this.

Horrors of the Brothers' War
Enchantment
If a player would lose life, they sacrifice that many creatures instead.
Whenever a creature dies, exile it and the top three cards of its controller's library.
Once per turn, each player may cast a creature card they own exiled with Horrors of the Brothers' War. Whenever a creature spell is cast this way, it gains haste and vigilance.
The brothers' armies lived only long enough to birth the next deployment.

That is so much better. Thank you good sir.
