Sunscourge Champion is really cool, as it fits into a lot of different strategies, providing two appropriately costed bodies for more aggressive strategies, good blockers plus lifegain for defensive lists and discard for decks that care about it
Activate only as a sorcery and only if an opponent has eight or more cards in their graveyard

I love Siege-Gang Lieutenant , but every planeswalker in this deck already produces tokens, and this officer can only sacrifice his own Goblins, so he gets the axe
Grixis (blue/black/red) Kefka plays into forced discard, and easily draws a ton of cards so that you keep your hand full while your opponents lose everything they have
