This build will work for a lot of tank but it is really good on Wonder Woman.

-Start early with a few tanky items like Metallo's Heart. (this will help the whole team too especially if they have attack speed champs like adcs or assassins)
-If you are really tanky after that and most of the other team is not hurting you, get a little bit of power damage and add more to your E then W.
-If a team stacks all attack damage then its good to get Mogo on top of Metallo's, Suit of Sorrows, and Bracers.
-If a gets all power damage or their main nuker gets really fed, Aegis can be very helpful.

Remember that your passive is a very useful skill and Diana's Bracers and Kryptonian War Armor both go very well with it. If your team needs you, and you get low you do not necessarily have to back; your health regen from all these should give you enough sustain to just pick up a health pack and return to the fight.
