Variant of Burden of Greed as Unbound hate.

Also hates non Unbound creatures due to it being an instant of course.

Having some sort of anti-unbound card like this is nice. I also feel like this works with a red strategy that wants to attack every turn anyway.

I feel like this is undercosted. Burden of Greed only cares about artifacts which not everyone plays, plus not every artifact even taps. Probably should cost the same or even

Increasing to seems right.

But Burden of Greed was a hate card in a set where almost all of your permanents could be artifacts. Against a dedicated Affinity Deck, if you survive till 4 Mana, you could deal a lot of damage since almost all of the lands count too. Unless it's a token deck, I doubt you could ever deal as much damage with this card as with Burden in a Mirrodin Match. Let's test it, if it is too oppressing we can change it.

Same logic applies to this, except it works against pretty much every deck. Unbound and untapping your creatures is a big part of this set, just like artifacts where in Mirrodin. Maybe this doesnt count lands most of the time unlike Burden of Greed but since everyone is going to be playing creatures it'll be as effective each time. I think it should cost at least the same.

It can't be as effective since it hardly ever counts lands. You are less likely to play creature lands here than artifact lands in Mirrodin. Least the same although is fair since you can't avoid it as easily as Burden of Greed.
