Hello, I believe this is the right place to post about this new card Karn, the Great Creator
So I was looking through the new set and saw this card and started crying. First off if paired with Mycosynth Lattice, which was rereleased about eight months ago in battle bond, essentially locks your opponents out of the game. Second its plus one is Karn, Silver Golem for four mana an slides right into any edh deck.
Finally its minus two. If all the previous stuff wasn't bad enough this turns card like Bone Mask, Eye of Yawgmoth, and Crumbling Sanctuary into card draw or harm to others. Then with enough mana Leveler gives us our whole deck and Mangara's Tome,Skyship Weatherlight, Myr Incubator and to some degree Phyrexian Devourer gives us tutor potential.These all let you grab pieces with Karn or get draw, next is some other things he can do.
Ramp, Surveyor's Scope you colorless deck will likely have the least lands
Extra turn Ugin's Nexus and possibly Gonti's Aether Heart with some fine tuning
Wish for anything Ring of Ma'rûf why not grab anything for little to no cost with recasting Ring of Ma'rûf or the exiled card, unless it's a non-artifact land
Fireball with artifacts Sword of the Ages cause some times you really want old cards to work
Sadly imprint losses connection to the card and makes the imprint useless
"If all cards exiled by an imprint ability somehow leave the exile zone, or if a card isn't exiled by an optional imprint ability, or if the ability failed to exile a card because it was countered, then it is possible for an imprint ability to have no exiled card to refer to. In this case, the linked ability associated with the imprint ability has no card values to refer to and will only do as much as possible. It may do nothing at all."
Finally exiling gravers for exiling on card is a dime a dozed mechanic.
Now you say, hey how are you doing all this over and over, I say Voltaic Construct and The Chain Veil with earns plus one and a three drop mana rock or two drop with Heartstone
God I hope this is an april fools prank.
Welp If you can think of anything else message me back to Brainstorm a way to fit this into a tighter meta than EDH and colorless tutor for it.
