Challenge

Using only cards from Ravnica block, cast Autochthon Wurm as quickly as possible.

Assumptions

You have perfect luck; for example, even after you shuffle your library, it’s ordered how you want. You may not assume anything about your opponent’s hand or library, except that he won’t do anything relevant.

Attacking “quickly” refers to both the turn of the game and whether you’re playing or drawing first. Turn three on the draw is quicker than turn four on the play, but not as quick as turn three on the play.

Solution to Last Week’s Puzzle

Rast once again provided the fastest solution to this week’s puzzle. He managed to flip all the Essences on turn two on the play as follows:

Play	Mana	Cards in Hand
Turn one		7
Forest		6
Orochi Leafcaller		5
Turn two		6
Forest		5
Mark of Sakiko targeting Orochi Leafcaller		4
Blazing Shoal targeting Orochi Leafcaller, exiling Myojin of Infinite Rage		2
Attack for 11	×11	2
Erayo, Soratami Ascendant	×9	1
Heed the Mists milling Sachi, Daughter of Seshiro and flipping Erayo		4
Goryo's Vengeance targeting Sachi		3
Tap Sachi for mana		3
Freed from the Real targeting Sachi	∞	2

Now that we have infinite mana of every color, we can draw infinite cards using Heed the Mists for draw and Stream of Consciousness for reusing our graveyard. From there, it’s easy to flip the remaining four Ascendants.
