[M19] Card Set Deckbuilding Challenge

Hello everyone

As always, every new expansion, we have a card set deckbuilding challenge. Apologies for missing out the Dominaria card set. As per the name suggests, this challenge wants you to look through all the M19 cards and tests your deck-building spirit! So, let us start with that the objective of this mind game. 1 lucky winner with the highest damage dealt will walk away with a M19 booster.

Objective: To deal as much damage to our opponent, from the start of the game until our opponent's 5th turn. The game only ends after our opponent's 5th turn, which means that it is possible to take multiple turns, and you also get to deal more than 20 damage to your opponent. Your opponent doesn't die due to state-based effects for having 0 or less life.

Rules:
You are participating in a M19 format which means that only cards from M19 boosters can be used. The link to XLN cards is here. This means that cards from the intro deck and buy-a-box promo are not allowed.
The opponent is the starting player, who is playing a deck with 60 forest lands, and lays a land on his turn, without other interactions.
Unlike the normal game of magic, you get to decide what your starting hand of 7 consists, get to decide what you would draw whenever you get to draw a card, get to decide what you would need to reveal if a card instructs you to reveal a card from your library.
(Eg, You need a forest on your draw step, you draw it. You get to decide what "wish" your Djinn of Wishes reveals.)
Golden Rule: If your opponent has a choice, the opponent will choose whichever option that is worse for you.
For ease of standardisation, your deck only contains 60 cards.
Feel free to ask any questions if you are unsure.

Your submission via pm/email should include:

1. Your name (if you want to be featured, or if you are the lucky winner)
2. Your decklist of 60 cards.
3. Step by step of your turns.
4. Calculation of damage. (Eg, Ans: 3: attack in turn 2, 3 and 4 for 1 damage each)

Please submit your answer through here.

You may submit more than one answer.

Feel free to discuss and share this Mind Game with others, and also through other mediums, but please do not spoil the the answer to others if you know have tried this game on another forum.

The game ends on 11.59pm on 22nd July 2018. The results with the maximum damage will be posted on 29th July on this post. Reader's solution with the maximum damage will also be featured here.

Turn 1: Draw Mountain
Play Mountain, cast Goblin Motivator

Turn 2: Draw Forest

Turn 3: Draw Swamp
Play Swamp, Cast 2x Druid of the Cowl

Turn 4: Draw Guttersnipe
Cast Vaevictis Asmadi, the Dire. Use Goblin Motivator to give haste.
Attack with Vaevictis Asmadi, the Dire, targeting my Mountain and opponent's random land, [for me] reveal and put my Omniscience into play, [for opponent] reveal and put random land into play.
Cast Guttersnipe
Cast Recollect targeting Mountain, trigger Guttersnipe and deal 2 damage
[Cast Recollect targeting Recollect, trigger Guttersnipe and deal 2 damage] - Loop

Repeat loop for as much as I want - Each loop does 2 damage to each opponent.
