Attack with Darksteel Colossus, then use Bloodscent. All or most of his creatures will be destroyed, and Darksteel Colossus has trample, so any leftover damage will go through. Also Darksteel Colossus would stay alive because it is indestructible.

Summon Darksteel Colossus, then bring out Darksteel Forge and Worldslayer. Equip Worldslayer to Darksteel Colossus. Darksteel Colossus will be an indestructible 11/11 w/trample that can easily clear your opponents side of the field.
