Well, there's always:

Creatures: 24
Savanah Lion x3
Isamaru x4
Dark Confidant x4
Spectral Lynx x3
Wretched Annurid x2
Jotun Grunt x2 (or just not at all)
Serra Avenger x3
Tombstalker x3

Spells: 16
Thoughtseize x4
Cabal Therapy x4
Swords to Plowshares x4
Vindicate* x4

Lands: 20

Redundant deck is redundant. It's just fast creatures, bombs, and a bit of disruption and removal.

*Other removal or something else would be fine here, I presume, but Vindicate is the best answer to artifacts and enchantments you could play MD, and it kills most everything.
