Karn, the Great Creator has inspired several new decks, but the breakout in terms of success and popularity is a combo deck based on Karn and Mystic Forge. Karn can tutor for Mycosynth Lattice or the Time Vault/Voltaic Key combo, and Mystic Forge can draw your entire deck with a Foundry Inspector and Sensei's Divining Top, or simply generate massive card advantage. With a huge amount of mana acceleration and the occasional Serum Powder, the deck is very redundant and consistent, making it very very likely to resolve one of those two four-cost spells on the first turn, either of which is very likely to lead to a kill on turn 2 or 3.
Vasu's exact list, posted above, placed four players into the top 8 of the recent NYSE 2019 event, and focuses entirely on speed and answers to common hate cards. Other players opt to take the list in a more aggressive direction, by adding more Workshop Aggro-style threats, or a more disruptive direction, adding Sphere of Resistance.
As of today, KarnForge is the deck to beat, and it would be a mistake to enter a tournament without a plan for it. Future KarnForge development will likely revolve around reacting to those plans.
