Your goal as Genji is to be a finisher and rack up Multikills 3+. Look for targets with around 20% HP, dash in and pop Deflect, most of the times this will kill a target quick enough to reset your SwiftStrike and you can dash out or through impassible terrain.

Hit me up in game if you'd like me to show you either of these builds.

With the SwiftStrike build, you can dive behind enemy walls get a kill with your SS and deflect, then dash out with the reset and Cyber Agility if needed.

Between Level 10 and Level 19, your means of racking up kills with DragonBlade is getting them low enough to then use your SwiftStrike to get a reset, and get the snowball rolling.

Once at level 13, if you can land all 3 shuriken hits, you can chunk down anyone you're dueling.

Once at level 20, instead of DragonBlading to get the enemy low and then swift striking, you can use swiftstrike to engage, then start hacking away with DragonBlade as any kill within 1.5s of a D-Blade swing will reset your SwiftStrike Cooldown anyway.

The Zanshin build plays a lot like the SwiftStrike build with the exception of getting an get out of jail free card with X-Strike as Genji is untargetable while it winds up.

Exceptional on Braxis against Zerg Waves, Goliath Camps and the Boss, also great against a heavy AA enemy team.

X-Strike or Swift Strike into the enemy team's damage and as they focus you pop your Deflect and delete them all. Make sure that any CC has been used before you do this and you can have some great plays.
