4. Blightsteel Colossus
Though he cost a hefty twelve mana to cast, Blightsteel Colossus is an absolute terror once he enters the battlefield.
This giant 11/11 golem has trample, infect, and also happens to be indestructible. Of all his noteworthy features, it's his ability to deal infect damage in the form of poison counters that is perhaps the most noteworthy.

Moreover, he's also indestructible, which means the venomous golem is almost impossible to remove from play.
It will take most players several turns before they can cast him, but as is often the case with good things, Blightsteel Colossus is worth the wait.
