This deck has hardly any removal, and while it's hell-bent on churning out a 20/20 and swinging in, that doesn't always happen. A card like Tabernacle with almost a dozen tutor effects is an excellent sideboard option against creature-heavy decks and Aether Vial strategies without more than a land or two, and because it acts as removal and lock-down in the same card, it's hard to argue against its value. If people are tapping mana to keep their creatures in play, they're tapping mana that could be used to cast spells to find answers. There's just so much redundancy built into the deck that using a single tutor to blowout or lock-up resources is perfectly fine if the situation requires it.
I'm not saying it's a must-have in every sideboard, but it's still one of the best options for utility with so much land tutoring and absolutely worthy of a flex slot. It doesn't matter if it doesn't tap for mana outside of Urborg, because you have Elvish Spirit Guide and Lotus Petal to accelerate and it's only a one-of. But as a one-of, the card's unique ability to unequivocally control the game on its own is worthy of consideration. Consider its application against Empty the Warrens, as well. If you're a turn short and have a combo piece in play, hand or another tutor - Tabernacle is perfectly fine.
