Like most Magic: The Gathering cards, the value of Legolas, Master Archer depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (The Lord of the Rings: Tales of Middle-earth)
Thin stamps are the reverse
Now, if you have a Skyclave Apparition or similar card that can exile the Sun-Crowned, thats definitely worth bringing in for games two and three
Consider this: if you are attacking with only three creatures, you can suddenly pump up a creature to being a massive danger for only three mana, using it as a powerful semi-removal spell or as a source for a ton of damage, depending on the situation
With it being a new mechanic, you won't see dozens of dual-ink cards, but there are five of them you have access to in the Amethyst and Steel starter deck
