Keg gets tokens and manlands immediately. That's pretty strong. Bomb is slow, but being able to hit what you want to hit with little damage to your own stuff is good. No 'walkers makes Disk even less attractive to me because it's harder to break the symmetry of it. I only run Explosives and Keg now, and don't see that changing anytime. Keg hitting the manlands is mostly what keeps it around.
It's too slow these days. Additionally, it wipes out your mana rock and other stuff. Leaves walkers behind, which can be both a benefit and a drawback. I like Powder Keg, Ratchet Bomb, and Engineered Explosives over it these days. They can take out tokens immediately and are more customizable in what they hit. Out of all of these, the only one that is a must-run is Explosives IMO. I love Disk, but unless I went up to an enormous cube size, its days in my cube are done.
