Power Monolith

 Deck by Gordon Andersson

Deck by Gordon Andersson

This is a combo deck that utilizes a powerful combo which Wizards actually thought was to powerful and therefore tried to stop on many occasions by issuing different erratas.

The combo works by combining Power Artifact with Basalt Monolith. This makes the Monoliths untap cost become one colorless and as it still taps for three colorless you are able to get infinite mana. This mana is then used to end your opponent with a huge Fireball or sometimes the classic artifact Rocket launcher (but do remember that Rocket Launcher has "summoning sickness").

The rest of the deck can be built in many ways but it usually uses a lot of counterspells to keep you alive and protect the combo. Sometimes the deck is built like a toolbox deck that uses Transmute Artifact to get the right answers or combo pieces like Basalt Monolith and Rocket Launcher.
