Infinite mana and BOOM

[Deathseide]

Using four cards, three if playing a mostly colorless deck, you can create infinite mana by playing a {Thran dynamo} {animate artifact} and {voltaic construct}.
Tapping the dynamo for 3, using 2 to untapped it via the construct.
Adding in a {gemstone array} to get the colors besides blue ( which you would need for the {animate artifact}).
One more addition and you got a pressure cooker set on infinite, the card {magma mine}, a veritable bomb.
Toss in some artifact retrieval and the whole thing is set.
