Wonderful puzzle well made, I could see a lot of players never considering how to win from a state like this. Fantastic lesson to learn

Hey! I am new to cEDH and am building Blue Farm as my first deck. Would you mind telling me the steps in this line? Thanks!

@SouljaBoyShinji, ||the solution to this is very complex! I couldn't find a bullet proof way and I'd love to here a better solution. The biggest takeaway is learning the interaction between Squelcher and Offer You Can't Refuse. Here is how I did it: 1. Tap Scrubland and Cast Culling the Weak, sacking Tymna, but hold priority and tap Otawara to cast Offer You Can't Refuse, targeting Culling. Because of Hexing Squelcher, Culling cannot be countered but you still get the treasures!! Culling resolves and we have BBBB + 2 Treasures. 2. We are going to crack 1 treasure and use BB to cast Intution. Hold priority and cast Flare of Duplication, targeting Intuition and sacking Hexing Squelcher. We now get to make 2 intuition piles: The first will be Lotus Petal, Mox Diamond, Chrome Mox. We will likely be given Lotus Petal. The second will be Breach, LED, and Sevinnes and we will definitely be given Breach as Sevinnes will just grab breach and LED allows us to crack LED for White and get both LED and Breach from the graveyard. 3. Use the remaining treasure and B to cast Borne Upon a Wind. Draw a card (irrelevant). 4. Cast Lotus Petal and crack it for Red and use our last remaining B for Underworld Breach. 5. Recast LED from the bin, exiling 3. Crack it and recast squelcher for protection. There was a window before this where we could be interupted. 6. Now crack LED for Blue, discard our hand and then recast Mystical Tutor, finding Brain Freeze. From here it's the standard Breach / LED / Brain Freeze line. Does this work?? ||

|| 1. Tap Scrubland, cast Culling the Weak sacrificing Tymna and holding priority 2. Cast Flare of Duplication, sacrificing Squelcher 3. Resolve both Cullings for 8 Black mana 4. Use B floating for Vampiric Tutor, holding priority 5. Tap Otawara, cast Offer on Vamp Tutor 6. Crack a treasure for U and use B floating to cast Borne, holding priority 7. Crack second treasure for U to cast Mystical tutor 8. Tutor for Beseech the Mirror, draw it once Borne resolves 9. Use floating BBBB to cast Beseech, bargaining Necro 10. Tutor for Underworld Breach and cast it for free 11. Use floating B to cast Dark Ritual from graveyard, exiling Marsh Flats, Vampiric Tutor, and Flare 12. Use floating BBBB to cast Beseech the Mirror from graveyard, exiling Necro, Culling, and Squelcher 13. Tutor for Lion's Eye Diamond and cast it, then crack it for BBB 14. Cast Dark Ritual again, exiling the lands we just discarded 15. Cast Beseech again to tutor for Brain Freeze 16. Cast LED again and crack for UUU to cast Brain Freeze 17. Win. ||

Thanks @Gamit180, appreciate the kind words!
