What are your broken Viktor builds

basically what the title says, i found that his powers sinergyze with a lot of relics and different builds, im personally going with echoing spirit, oath of the guardians and star gem (this is 6 star viktor). you play him on turn 2, making sure that the card played is created by echoing spirit so it duplicates, then you can play a discounted level 2 champion that will also get duplicated, recieve augment and progress viktor´s level up (if you havent already leveled him up lol
