Bullet paradox with explanation

if you are new just buy 3 from left and boots, otherwise choose depending on lane and preference
If you can get next tier items quickly make sure to do so

either kinetic for movement or mystic for burst dmg or both

decent items you wanna get eventually but feel free to skip

However if you can afford a 4tier item - always go for crippling headshot or glass cannon

Choose one of them

But 99% of the games you don't

You don't wanna upgrade any abilities until you get your ult - why? Because 2nd upgrade of the swap gives you a flat +100dmg and if u can get it immediately after u get your ult it'll make your early game op
Then max carbine, wall and grenade

Remember this is a bullet + headshot build so you always wanna hit the headshots to maximize your damage, then as always with paradox u place a wall and ult throught it to deal as much burst, heal and in the late game silence with the last upgrade of the wall then get away to safety with warp stoneand shoot
