Brainstorming

Nether spirit alone, with it’s ability to reanimate as long as there is no other creature card unless this card is already a combo in itself. This card is perfect for a pure spell deck, usually blue deck with a lot of counterspells in it are a better choice. You have nothing to worry about playing any creature all you need to do is to discard the Nether spirit and your good to go casting spells like instants and sorceries. The Darksteel Brute are just for backup, helpful enough to backup your only creature without disturbing it’s ability to reanimate by itself.
