Syr Gwyn, Hero of Ashvale + Haakon, Stromgald Scourge + Lotus Ring + Tannuk, Steadfast Second

Syr Gwyn, Hero of Ashvale

Haakon, Stromgald Scourge

Lotus Ring

Tannuk, Steadfast Second

How it works

1. Activate Lotus Ring's equip ability by paying 0, attaching it to the Knight.
2. Activate the Knight by tapping and sacrificing it, adding three mana of any color.
3. Cast the Knight from your graveyard by paying its mana cost.
4. Repeat.
5. If the Knight has mana value 2 or less, this combo nets infinite mana.

This loop turns the graveyard into an engine by letting you repeatedly sacrifice and recast your creatures at no equip cost. Syr Gwyn, Hero of Ashvale makes this possible by setting the equip cost of Lotus Ring to zero for Knights, allowing the equipped creature to immediately tap and sacrifice itself for three mana using Lotus Ring's ability. Once it hits the graveyard, the static ability of Haakon, Stromgald Scourge lets you cast that Knight card straight back out of your graveyard. Meanwhile, Tannuk, Steadfast Second ensures your recasted threats can re-enter the battlefield with haste, keeping the loop instantaneous and explosive if the Knight's mana value is low enough to net positive mana.
