Good choice, it would still be under 2k spirit 
Just for your information:
I added a short list of good rares to craft for L’Kian to the wiki:
Golem Metallurgist (for any Golem deck)
Manaforger (for Arcanyst decks)
Flameblood Warlock (for many Aggro or Burn decks)
Celebrant (for any Golem / Swarm deck)
Zyx (for Swarm decks)
Azure Horn Shaman (for Maehv decks)
Abjudicator (for spell heavy combo decks)
Cannon of Mechaz0r (for Mech decks)
Sword of Mechaz0r (for Mech decks)
Prismatic Illusionist (for Arcanyst decks)
Sojourner (solid card draw option if you don't have / like Spelljammer)
Lightbender (great dispel, sees play in many different decks)
Owlbeast Sage (essential to any Arcanyst deck)
Blue Conjurer (great in Arcanyst decks)
Grimes (good card, can be game winning, a lot of value for 6 mana)
EMP (often a great answer to many decks)





That means the proper description of how Gambler works would be:
