Grim Monolith

goes infinite with mana reflection in play, easiest combo ever

This card is very great since unbanned (1 July 2010)..... great combo with Voltaic Key and the others artifacts. Also, you must bring 4 in the artifact deck....

i have one of these cards signed ..whats it worth??????

Quite possibly one of the most played cards while it was legal in Block and T2. There weren't many decks around that didn't run this.

Thanks for that Jimmy. You've truly grasped the power of this card and make no mistake.

Awesome card that can be comboed very easily to a fat mana advantage.

This card is a killer it can bring out a strong monster so easy if you have 6 mana on the field that can be 6 new mana by only tapping 6 mana.

With just power artifact, you can generate unlinited mana with this card. Power Artifact lowers the activation of an artifact's ability by 2, and the Monolith generates three. Very good deal, but I think power artifact is banned or restricted. :( Still, well worth the money. ;)

This card is extremely good!

Make It a creature and combo it with at least two Heartstones and boom Infinite mana!!!

Only good if you got 4 of voltaic key, then use it to do it all over again.
