If you are facing against a physical God, start with shield. If against a magical god, start with rune. If the enemy team comp lacks CC get shell instead of beads. First item will be Ashwhorl Acorn, then followed by either Breastplate or Genji's (depending who you lane against).
Combos: If you are in melee range, stun with your 3, move your way around them, use your 1 to knock them up and displace them, auto, use your 2 (beads if needed to avoid interruptions), auto, and use your 2 again. Combo 2: If you are out of melee range, use your one, auto, use your 3, auto, use your 2, auto, and use your 2 again (beads if needed to avoid interruption. With Gengji's proc and rat's passive, you should be able to dash and knock up the same opponent twice. Make sure you target the enemy back liners (Mage or Hunter) in team fights. With this build, you can also abuse the junglers with your insane healing.
Swap Draconic Scales for Resolute Mantle if they enemy team comp lacks any form of dot damage or when they have high CC. The more tenacity you have, the easier it is to get your abilities off (which means more healing)
