I'm going to talk about the most crucial aspect of the deck that makes a difference between a victory and a loss most of the times. That is, the timing to play Tortollan Pilgrim safely and turn the infinite engine on.

First of all, what is our aim? We want a 1/1 copy of Tortollan Pilgrim for our next turn. If we get to that next turn, and the opponent doesn't run anti-secret techs, it's GG. If we lose both Tortollan Pilgrim to prevent opponent's lethal, it's game over.

In the trivial case, mostly happening vs control decks, you just play Tortollan Pilgrim as soon as possible, usually turn 8 or slightly earlier thanks to any mana ramp. 

Most matches, specifically vs aggro, won't allow you to do that safely, because if you just do that, you are dead on board. In these cases, playing Tortollan Pilgrim safely means you need 2 more mana. Why? After playing the first full cost pilgrim, you are going to play another 1 mana 1/1 copy that will give you now 2 copies. Then you play another 1 mana copy to select Ice Block, and stay with another copy in your hand. 

But 2 more mana means basically having to resist 2 more turns. Vs aggro, that can be troubling. So how do we play? First of all, if we are able to have an untouched Ice Block on, because we drew 1 copy of it or because we got it from Arcane Keysmith, we can safely play Tortollan Pilgrim, and secure our win. For this reason, sometimes drawing Ice Block or even keeping it on mulligan can have its bright side.

In alternative, if we are back to the wall, we can try another play if we have both Tortollan Pilgrims in hand (happens quite frequently thanks to Lorekeeper Polkelt) or one copy of Potion of Illusion. We play the first Tortollan Pilgrim and select Frost Nova. We pray that the opponent does not have direct damage to finish us, or kill the pilgrim on board. On our turn, we copy the pilgrim with Potion of Illusion or the other one we had in hand, and have our engine on. 

In all this, you can anticipate the turn you go off thanks to Escaped Manasaber and Emperor Thaurissan, so you need to carefully prepare your plan with many turn in advance. I'll deal with this aspect of mana ramping in a specific section.

I'm sorry I don't have enough time to make a longer guide right now, but there are a lot of aspects to explain, and it would be a very long guide. I will need to talk about mulligan, mana ramping, board and hand space management, tech cards, otk count, educated elekk interaction, specific matchup strategies. In the meantime, the informations above, I think are the most important to start piloting the deck in an optimal way. Stay tuned for the rest.
