As dragunity user, luin indeed a useless card unless you prepare the trap which cant be added.
Im not expecting Areadbhair or other new cards, but at very least i hope they release crystal wing. Limiting divine lance just because trunade is kinda absurd, as they can ban trunade for all i care
It was available through selection box sometimes before that. I'm pretty sure of it. Because I don't think I would have spent so much on a selection box during that period if it wasn't for something at least as strong as trunade. Unless it was for another card. I don't remember very well.
And xyz era hasn't even come yet. I guess i could hope more for Areadbhair earlier then, as Aschalon came sooner than Crystal wing in Duel link in spite of its card release date
