But in Commander, 5WWU isn’t that restrictive of a casting cost. It's especially worth casting by turn 8, as well, since the life-gain that one would get from Filigree’s effect by that point will be substantial. With artifact cards like Sol Ring, Swiftfoot Boots, Lightning Greaves, Darksteel Ingot, and Sensei’s Divining Top a part of many Commander decks, you’re talking about double-digit life gains whenever this card hits the board.
Also, while a 4/4 flyer doesn’t seem impressive on the surface, there are so many pumps for artifact creatures that exist in Commander that this Angel probably will be a good deal beefier when it hits the board. Add to that we have yet another Angel for Angel lovers, and one that’s light on the wallet (they sell for only about 50 cents USD a copy.) Filigree Angel was also reprinted in one of the Commander 2013 and one of the Commander 2016 decks.
While hardly one of the best artifact creatures around, Filigree Angel has its uses, especially in an artifact deck that cares about life-gain. There are quite a few Commander decks out there that revolve around artifacts. What better way to keep yourself in the game than double-digit life gain? In particular, the popular Breya, Etherium Shaper plays Filigree Angel a lot. But if you play any artifact Commander deck in White & Blue, you should definitely consider slotting this artifact angel in somewhere.
