Minimus Containment, Grim Bounty, Magic Missile are all removal spells. Magic Missile is very powerful, very frequently able to kill 2 creatures. Minimus Containment is a Banishing Light variant that is a little more exciting. Grim Bounty was swapped in since black had not had any sorcery speed targeted removal spells in the cube.

Battle Cry Goblin, Targ Nar, Demon-Fang Gnoll, Red Dragon, Ravenous Lindwurm, Owlbear. Red/Green has been historically under-drafted in this cube. Battle Cry Goblin and Targ Nar reinforce the power matters-ness of the pair while being very strong cards. Red Dragon, Ravenous Lindwurm, and Owlbear and some good late game cards for the deck (and other adjacent color pairs).

Sepulcher Ghoul, Shambling Ghast, Reaper's Talisman. Black/Red has also been slightly underdrafted. Sepulcher Ghoul and Shambling Ghast are additions that can go in any Black/X deck, but should work best in . Reaper's Talisman is a very powerful black equipment while Malefic Scythe usually had a hard time making the cut.

White Dragon and Scion of Stygia are the last two swaps. Frost Lynx might have been slightly too good for , and Scion is less good at being an offensive card in the late game. Bulwark Giant was never played in any decks and White Dragon is an exciting new card from AFR that fills a similar role the giant was intended for.

Overall I ended up making a lot more swaps than I thought I would and this set came at a great time for the cube since was in need of some good cards. There's talk of bringing the cube up to 540 cards and also the possibility of changing the and archetypes. I am very excited to see what the Innistrad sets bring!
