Never Ending Protection

[xStrayKnightx]

 {Aegis Angel} + {Indomitable Archangel} + {Swiftfoot Boots}.

Indomitable Archangel enters the field, Metalcraft inactive. Cast Swiftfoot Boots, momentarily equip to Indomitable Archangel if you want. Cast Aegis Angel, choose Indomitable Archangel as the indestructible permanent. Equip Swiftfoot Boots onto Aegis Angel, and, assuming you have at least two other artifacts on the field, they're all protecting each other.

Swiftfoot Boots gives Aegis Angel hexproof.
Aegis Angel makes Indomitable Archangel indestructible.
Indomitable Archangel gives Swiftfoot Boots shroud through Metalcraft, assuming it's active.

Aren't circles in their very nature never ending? 😝😁
