So first I want to state that I feel like if you don’t build a deck heavily around the healing synergy you are always going to end up with a bad version of something that would work better with argeon, this is how I feel about it you may agree or disagree but now that you know my logic you will have a better understanding of my card choice:
Azurite lion: Without the BBS of argeon this card is not nearly as exiting , it is a decent card by itself but we need to clear space to have some healing synergies so I cut to make space for lightchaser and fiz.
Windblade adept: This one is a bit more debatable, but once again I try to maximize as much as possible on healing synergies , lightchaser is amazing in healyoanr, if you play it in the back your opponent will have to trade a card to deal with it and if he doesn’t then the card will be much bigger and scarier than windblade if your deck is built properly.
So if you go -3 windblade -3 lion +3 fiz +3 lighchaser, you make yourself slightly weaker in early game, but everything is in your deck will work much better , healing pay off will fell like real powerhouse.
If you rely on z’iran BBS to get stuff going you are dreaming, the BBS of zi’ran is just a bonus, most of the time you’re not going to be able to use it, this is why you need cheap heal enablers like elixir/fiz /mystic
Sun bloom: I like lightbender better , dispel more stuff , range is usually irrelevant and it provide board precense which is number 1 priority in healyonar.
Lucent beam: Terrible in your deck since you have so few healing , in mine it’s ok but beam is most likely an aggro card and I choose to go for a more midrange approach.
Day watcher: It is a win more card , if you manage to make it work that mean you have a board which mean you are already ahead , terrible card otherwise.
Arclyte regalia: In a healyonar deck you have to make space for healing synergies, which mean you have spot left only for the very best lyonar cards which are: holy immolation, silverguard knight, ironcliff guardian. Not only regalia is generally not as good as those 3 cards but it doesn’t help the game plan , holy immo is a heal and is just too good to come back when you are behind, ironcliff and silverguard will provide the board presence you need to make your BBS effective.
Sun sister: Worst healing pay off , sunriser and lightchaser are just WAY better , 9 healing pay off is enough and you need to balance between healing pay off you use when you have the opportunity to heal, and powerful pro active threat that are good on their own.
Circle of life : I like it because it is good against Songhai, but its expensive cost make it hard to combine with a heal pay off. I decided to cut them for more board presence.
helyx stormblade: I like it, I preferred to go for ironcliff since I play divine bond. I believe the classic DB/ironcliff/tombstone is still what makes lyonar good , and the BBS of Zi’ran is a guarantee that you are going to get some huge DB hits, won me too many games to be ignored.
Ruby rifter : Like the card but not enough to put it in my deck.
I can easily see how you struggled against Songhai since you play 0 martydom.
