How it works
Activate creatures you control by tapping them, adding at least 1.
Activate Emry by tapping them, allowing you to cast Sky Hussar from your graveyard this turn.
Cast Sky Hussar from your graveyard by paying 3.
Sky Hussar enters the battlefield, untapping all creatures you control.
Activate Krark-Clan Ironworks by sacrificing Sky Hussar, adding 2.
Repeat.
By blanketing the battlefield and your graveyard with artifact types, Encroaching Mycosynth turns your entire board and your recursion pieces into eligible fuel for Krark-Clan Ironworks, which cheerfully converts your sacrificed permanents into raw colorless mana. This mana engine powers Emry, Lurker of the Loch, whose affinity and tap ability let you repeatedly pull Sky Hussar right back out of the graveyard. Every time Sky Hussar resolves and enters the battlefield, its triggered ability untaps all your creatures so you can tap them again for mana or activate your other resources, allowing you to feed the Ironworks sacrifice loop indefinitely.
