You can still cast it on the opponent's turn to remove summoning sickness, read the rule again:
302.6. A creature’s activated ability with the tap symbol or the untap symbol in its activation cost can’t be activated unless the creature has been under its controller’s control continuously since his or her most recent turn began. A creature can’t attack unless it has been under its controller’s control continuously since his or her most recent turn began. This rule is informally called the “summoning sickness” rule.

doesn't give haste, so better to play it during your opponent's turn.

If you have it, use it. Great card; it's like picking a creature to draw but better!
May the fans continue to make cards!

Combo with tutor effects (Like Worldly or Momir Vig), you can play toolbox with your creatures and better yet, do it again once it returns to your hand. Mystic Snake, anyone?

If you play it during an opponents turn, it still has summoning sickness, so it can't tap. It can still block, but it goes back to your hand at the end of turn anyways, so it will have summoning sick when you summon it again.

Forgeling: nope, casting this in opponents turn doesn't help. The creature still has the summonig sickenss. See rules, 302.6, summoning sickness.

I like this card, but I'm never able to make it work for me as well as I imagine it should...

Not bad when combined with the flicker support from Return Avacyn.
