chaos cards mtg Throes of • Modern Horizons (MH1) #150 reselect its target at random Chaos Orb - Unlimited Edition

If Wizards of the Coast decides to print must-have 1 cost legendaries in the next set, it might be time to get a Mox Amber of your own

It could help you stabilize versus aggro though, especially if you can trade off the body afterwards

If you have a lot of relevant permanents such that their Detention Spheres always have targets but yours might rarely have non Detention Sphere targets, you might need Banishing Light so that you can remove their Detention Spheres with a card that would otherwise be dead, having no other target than Detention Sphere

Not completely unheard of, but you probably won't want Ur-Dragon as the head of such a deck
