Limit Break has a few Soldier cards, but its not a tribal deck centered around Soldiers
Card: Trench Wurm Set: Invasion # Decks Running It: 66 Price: $0.25 Hill Giant stats are nothing to write home about, but a built in Stone Rain
Now, with the practical details out of the way, lets dive into some cards that are likely to shake up the various constructed formats
These lands tap for colorless mana by default, but they can be sacrificed for one generic mana to search your library for a basic land of one of their associated colors
Gruul is known for dealing with big creatures, and Electrodominance will definitely shine when you spend 13 or more mana to dome someone and then cast a Worldspine Wurm
This deck also made me appreciate the heck out of Corpse Dance, a card I rarely played with before but I think is legit good, its repeat instant-speed reanimation that gives the creature haste and while it does exile at end step, you can avoid this by just sacrificing the creature beforehand
