Infinite Conquest with Loki-Darkhawk
CL 10K, infinite every season, usually good for 1-2 infinite conquest borders each season.
I've won Conquest with quite a few different deck types ... including Move! I enjoy using Loki in Conquest but usually find that he is hard-countered by MMM.
But no MMM to be found in the current meta! This run I faced Destroy, Arishem, Sera Control, Arishem again, and Negative.
Loki-Darkhawk feasts on Arishem. Playing either Loki or Darkhawk will often get you the win. Usually going tall is needed as Arishem can go wide so easily. Cosmo is useful to protect your massive Darkhawk, which can otherwise easily solo a lane.
Destroy was weak to Shadow King and I got lucky to also Loki their Knull more than once.
Negative folded hard to Shadow King and Cosmo in the final match, as well as Snow Gaurd turning off Limbo.
I usually run Cable with Loki, but that has negative synergy with Darkhawk, and so Valentina replaced. Valentina also loves Shadow King to reset the power of the generated card.
Sersi is a great surprise play, often to convert a Rockslide or Mirage into something more useful.
Good luck!
