Despite slogging through some of the most awkward topdecks I've ever seen with this deck, I manged to end my final game last night in a draw.
I kept an opening hand with Enduring Ideal. On my third turn, I cast Tempt with Bunnies and got three hits, but failed to topdeck a fourth land. Then I failed to again. So when Search for Azcanta had six cards in my graveyard and revealed Moat, I chose to bin it even though it was a card I knew I'd probably like to draw soon. I needed mana immediately if I was going to stay in this game. Over the course of the game, I topdecked Decree of Silence, Humility, Dovescape, Kumena's Awakening, and Sandwurm Convergence. Most of the enchantments I'd want to fetch with Enduring Ideal were sitting in my hand. One of my opponents tried to use some creature with a trigger to randomly exile and poach stuff off the top of my library. I didn't like that, so I cast Perch Protection and gave his biggest threat a free extra turn. The guy who got an extra turn managed to ultimate his Ral, Crackling Wit. He hit a bunch of permanents with the card "Suspend" in order to clear away blockers, but actually didn't manage much damage. I cast Humility to make sure that whatever creatures he used, they wouldn't have abilities to deal with mine, while I bought time. The other two players were actually a lot more dismayed about the Humility than the guy who was winning before. One conceded when he realized that he couldn't get his creature's EtB trigger through my enchantment. The turn looped around to me again and I finally cast Enduring Ideal, just immediately going for Divine Intervention. The player after me didn't see any outs and didn't stick around to see if the game would end in a draw, but it did. I had too many blockers lined up.
Humility wasn't very satisfying in this game, but it did get me there, so I'll take the win. Well, the draw.
