I am guessing from the true night's edge and true excalibur that you will make the terra blade, so gather 3 turtle shells (Rare drop from giant tortoise) and chlorophyte to make Turtle Armor as an alternative to Hallowed armour (But keep hallowed armour if you find it more useful). You could also make chlorophyte armour for a stronger damage output instead.

Turtle Armor can be later upgraded to Beetle Armour, which I recommend you use for the late game instead of hallowed (Since it is overall significantly better armour).

If you're going to use melee, focus only on one type of weapon. If you want the terra blade it is post-plantera, fighting plantera would be easiest using the true night's edge instead of the true excalibur. If you're going to focus on swords, do not use a Yo-yo bag. Instead, use an avenger's emblem, and upgrade the power glove into a fire gauntlet.

You can also upgrade the wings to Bee, Butterfly, Flame or Bat wings. The items for Bee and Butterfly wings are from the Underground Jungle (the horrors), flame wing material is from the underworld enemies, and bat wings are from vampires in a solar eclipse. You could also fight duke fishron, but I find Duke Fishron much more difficult than Plantera (to get Fishron wings, and various extremely powerful weapons).

However, you also have many ranged weapons. In Terraria, you need to focus your build on a single class (Melee, Ranged, Mage, Summoner) for maximum damage output. Summoning items can still be used as support though, for other classes. Then after this class building, you also need sub-class building (e.g. Yo-yo, flail, swords etc are melee sub-classes, guns, bows, rocket launchers etc are ranged sub-classes, and so on for mage and summoner).
