I was thinking items like gunblade spirit visage and deadmans as your core with an abyssal and voidstaff later. I feel a gunblade would work well on him as it provides some pseudotank with a bunch of stats he can use. With his upped ratios any stats should do more then in the past.
Trinity > Luden's Echo into full tank is probably the best combo.
gunblade is an ok item, but by itself is underwhelming and the healing you get from it isn't substantial by itself.
void staff is ok, but without ap to back it up its not so great.
Abyssal is probably the other option as its both tanky and gives you some ap and mr reduction.
that said, Trinity is bought because its the best single item spike for a sheen item. and luden's is the most burst you can get from a singular ap item.
trinity > Luden's > full tank is good or
trinity > tank item > luden's > full tank.
you can build anything on that champ and do dmg untill lvl 11.
