Courtesy of Wizards of the Coast (WotC) and MTGGoldfish, check out the ultimate copy machine from Zendikar Rising — Lithoform Engine!
Likely to be a fan-favorite in casual formats, Lithoform Engine can copy just about anything for the right mana investment and coupled with the right cards, Lithoform Engine can easily be used multiple times per turn.
For two mana, Lithoform Engine can copy an activated or triggered ability. Enter the battlefield abilities gain massive value here, as Lithoform Engine essentially lets you cast the card a second time for only two additional mana.
Acting like a reusable Reverberate, copying an instant or sorcery is the more common copy ability of the three seen here, but arguably the strongest.
While expensive, copying a permanent spell you control is wildly powerful, and is likely to lead to some very wild battlefields. Copying a permanent like Mirari’s Wake could generate a ridiculous amount of mana, leading to even more off-the-wall interactions as the game goes on.
