G/W/U Troll Worship - A hexproof combo deck (Modern)

I engineered this heap of cards starting out from a deck I originally found here: http://www.mtggoldfish.com/articles/budget-magic-84-65-tix-modern-troll-worship

Over time, it sort of evolved into a combo deck. I tried for a long time to make it into a sort of midrangey bogles deck, but it was always too slow, and when I found Commune with the Gods, things clicked together.

What this deck wants to do:

• win by either "bogling up" a troll and hitting for lethal in a few turns, or by deploying a Worship and a hexproof creature and building up a threat that wins the game more slowly
• dig for its combo pieces with Serum Visions, Commune with the Gods, Opt, and a scry land
• have a few answers/blockers against decks that would otherwise win too fast (Path, Sylvan Caryatid, regenerating trolls)

Key cards are:

• Commune with the Gods: digs 5 cards deep, and has a 60% chance of finding 2 combo pieces, and 90% of finding one (if you include all hexproof creatures)
• Sylvan Caryatid: ramp for a turn 3 Worship, a decent defender, and a hexproof creature to activate Worship with
• Unflinching Courage: together with a regenerating troll and a backup creature almost unbeatable

The sideboard has 3 Swan Song, since it counters almost everything that can destroy a Worship apart from creatures like Reclamation Sage/Knight of Autumn or planeswalkers, 4 Leylines against unfair decks that would win too fast, 2 Damping Sphere for the same thing, and two Rest in Peace and 2 Stony Silence. It is tuned against non-creature heavy decks, since those are the ones most likely not to care about my creatures and able to win fast since I don't have any kind of interaction apart from Path to Exile. Commune with the Gods can find 8 of my sideboard cards. Pongify for the LOLs and additional creature removal.
