Welcome to Gaia! ::

might I suggest a mirrorworks?

Here's my current Golem deck:

Creatures:
Blade Splicer x2
Adaptive Automaton x3
Master Splicer x3
Wing Splicer x2
Phyrexian Metamorph x2
Precursor Golem x4
Maul Splicer x2

Non-Creatures:
Everflowing Chalice x2
Emerge Unscathed x3
Mutagenic Growth x4
Apostle's Blessing x4
Tezzeret's Gambit x2
Birthing Pod x3
Karn Liberated x1

Lands:
Glacial Fortress x3
Sunpetal Grove x1 (Need more)
Plains x11
Island x3
Forest x5
----------------------------------------------------------------
What I like about this deck is that it is faster than the other version, but I still have problems with keeping up with most opponents. I like the idea of Birthing Pod, but I need more stuff.

I'm thinking about cutting a Master Splicer for another Adaptive Automaton, taking out Karn for something else (maybe another Tezzeret's Gambit), and dropping the Everflowing Chalice for Steel Overseer. I would also like to add a couple of Sun Titan's as I saw them in a similar deck and thought it was pretty cool, but I'm not sure if it is practical in my deck.

Thoughts?

Land isn't plentiful enough in this deck to run either, but I appreciate the thought.

I think the issue right now for me is that there is a lot of cards I would like, but I don't know what to cut.

I really enjoyed the golem cards, but they all seemed to high-costed for me...and it looks like you're experiencing much the same thing. I think the two big things with your deck are 1.) slow early game and 2.) clogged high mana slots. Honestly, I'm almost tempted to tell you to completely drop most of the green from the deck, keeping just Sunpetal Groves and Birthing Pods, though I do like your other green cards in the deck. 2-color is just that much easier to run, since Alara is out of Standard, and this looks to be a Standard deck. Taking a look at your newer decklist, here are some suggestions:

Creatures: I would drop 1 Precursor and the Phyrexian Metamorphs for sure. Grab some colored myrs (Copper, Gold, and Silver) for the early game blockers and mana ramping. Solemn Simulacrum could also help the ramp and, bonus points, it's also a golem. If you want something that acts like a Metamorph, try the cheaper Phantasmal Image. You can grab a 3P/T golem for 2 mana, regardless of what happens to the Splicer you copied (if the Splicer is anything but a Master Splicer, you're not getting further benefits anyways), or grab extra mana by copying a Myr or Simulacrum, or just copy something nasty your opponent just played.

Non-Creatures: Emerge Unscathed and Apostles Blessing do pretty much the same thing. I would use one or the other (my vote goes to the Blessing...which you should use to punch through your opponent's defenses more than protect your creatures), and maybe only 2 of them, and fill extra slots with Oblivion Ring or some kind of counterspell. Everflowing Chalice should go (too mana-intensive to make it worth while), and I would replace Tezzeret's Gambit with Preordain and/or Gitaxian Probe to help speed your early game. Planeswalker-wise, dropping Karn seems solid. New Jace could work, but he's just another card in your 4-mana slot, and he's stupid-expensive.

Land: If you go the greenless route, Kabira Crossroads might be helpful to offset the Birthing Pod life-loss. Other than that, you already noted you need more Sunpetals, and that would be my only real suggestion here other than, if the myrs and Solemns work out, dropping down to no more than 22 land.

I have to admit, I now see why you put so many protection spells in the deck. I didn't realize that Precursor Golem's thing about one target, all target meant it hits every golem you have, not only the ones it created. In that case, I definitely support them as pseudo-counters and even further help punching through an opponent's forces. Same with Mutagenic Growth.

There is. Its called Elixir of Immortality. 3nodding
