There are not that many Xtra HERO Link monsters. It kinda sucks, especially since Isolde and Summon Sorceress are the only solid Honest Neos support links out there. I wanted to try out two different cards that I thought were useful.
Xtra HERO Distress Instrumentalist
Dark / Warrior / Link / Effect
Attack 1800 | Link -2 (BL, BR)
2 "HERO" Effect monsters
When this card is Link Summoned; add 1 Spell Card that specifically lists "Fusion Summon" in its text, from your Deck to your hand. You can only Summon 1 "Xtra HERO Distress Instrumentalist" per turn.
Xtra HERO Angelic Muse
Light / Warrior / Link / Effect
Attack 2100 | Link -3 L, R, B)
2+ "HERO" Effect monsters
If a "HERO" monster is Normal or Special Summoned to your zone this card points to; Draw 1 card. You can only activate this effect of "Xtra HERO Angelic Muse" once per turn. This card gains 200 ATK for each "HERO" monster Summoned this turn. If this card attacks a Defense Position monster, inflict piercing damage.
