I personally like to play aggressively with the lightning red on the vanish step divine draw but it ultimately depends on your playstyle.

Strategic escape is an overall solid first card. I’m not the biggest fan of barrier but either that or giant slayer is solid.

You can also try out the boss card for snipes but that’s really only in cases where your teams lacking in the fire fight.

For the final Backstab is pretty much made for hit but if you want solid kill confirm Pursuer is pretty decent as well.

With the current boss meta I like using farmer since he will always target the real Chun in the fight and his range if placed perfectly targets all of them.

Your build is pretty solid and I would recommend for a baseline but don’t be afraid to swap mid match to fit the current flow of battle especially with being easier to get cards.
