MTG Salvation

I have wanted to abuse the combo between Puresight Merrow and Paradise Mantle for the longest time. Here's what I've come up with:



Okay, so this make look like a conglomeration of oddities, but there's some method here, I swear. Puresight Merrow and Paradise Mantle allow you to churn through your library as you look for a card to exile with Shelldock Isle. Shelldock Isle allows you to cast the card without playing its mana cost, so either Emrakul, the Promised End or Emrakul, the Aeons Torn are perfect here. But since we already have the option to churn through our entire library, why not put Laboratory Maniac in as well?

Angelsong, Hindering Light, and Censor all offer a bit of protection for us to live through our game plan, but they also offer potential wins with a Laboratory Maniac in play. See Beyond let us send away an Emrakul since we're never going to be able to cast it if it starts in our opening hand.

The ideal scenario goes a little something like this:
T1: Land, Paradise Mantle
T2: Land, Puresight Merrow
T3: Tap a land, equip Merrow with Mantle, activate until Emrakul, the Aeons Torn is on top, then play Shelldock Isle to exile Emrakul
T4: Activate Merrow until there are 20 or less cards in your library, then activate Shelldock Isle to cast Emrakul and get your extra turn
T4b: Beat face with spaghetti monster

Obviously this is not perfect, but I feel like it's a start. I have been wracking my brain for a way to speed things up a bit without going too heavy into just janky cards that just take up space.

Let me know if you guys have any ideas!

Hindering Light Seems Overshadowed By Remand. It Also Seems Like The Deck Needs Some More Cantrips I.e. Serum Visions As You Can Still Go Off Turn 3 If You Cantrip For A Piece Of The Combo On Turn 2, Additionally Emrakul, the Promised End Seems Strictly Worse Then Emrakul, the Aeons Torn And It And Laboratory Maniac Should Be Cut For Space For More Enablers. Imo.
