Depending on the format, you can use your trusty turn-1 Llanowar Elves to set up your future plays, or you can use cards like Elvish Archdruid and Priest of Titania to produce tons of green mana depending on the number of elves you have on the battlefield

That's very powerful in going wide decks like midrange, Zombies, Boros Aggro, Selesnya or Orzhov Tokens, and more

Why not focus on Abzan itself

You cast a second Shadowspear, and the spell resolves

This opens up the door to a huge array of powerful combos, but its completely viable in fair decks as well, easily ramping out a power play or two on Treasure mana alone
