JST with a focus on lifesteal for Katra procs. JST gets access to Banish and Slay at 2 mana which are incredible. with things having their cost reduced banish also hits units and relics with original cost of 5. Safe return at 0 mana makes the card hugely impactful and flexible, saving your units from removal and resetting ambush units, stonepowder alchemists, and Combrei Healers. Stand together and Vara's Choice were cards i wanted to try, and after playing with them i like the 2/2 split. Invoker would probably get the axe for me in lieu of another solid threat, maybe the 4/4 overwhelm aegis, since if you're getting large sums of life you're likely winning, though the random 1/1s and 2/2s aren't horrible. I went with a heavier focus on Shadow and Time influence to make up for the double cost of Katra, Karmic Guardian, and Ayan. I found that you more want the influence number than power number.
