Leyline of Kodama's Will

Enchantment
If Leyline of Kodama's Will is in your opening hand, you may begin the game with it on the battlefield.
Instead of casting a creature card you may pay

and put it on the battlefield, where

is its converted mana cost.
Creatures you control have Flash.
And, now, for a totally non-creature helping Leyline:
Leyline of the Aerie Kingdom

If Leyline of Aerie Kingdom is in your opening hand, you may begin the game with it on the battlefield.
Whenever an enchantment enters the battlefield under your control draw a card.
Each other non-Aura enchantment is a flying creature with power and toughness each equal to its converted mana cost. It's still an enchantment.
Interesting, but I feel the first one is just way too close to Leyline of Anticipation. Nothing too special there.
Second one is Enchantress Presence AND Opalescence on crack. Imagine you open with 2 of them, swing for 8 on turn 1, good luck dealing with that.
Granted, Opalescence is pretty much outdated and could be reprinted in a more powerful version, this just seems a bit too much for a free spell. I don't think Leyline allowing easy card-draw are a good idea in general, potential for them to be busted is high.
