Lila Brightfeather

Affinity for artifacts (This spell costs {1} less to
cast for each artifact you control.)
Whenever Lila Brightfeather becomes the
target of a spell for the first time each turn, create X 2/2 black drone artifacts with flying, where X is equal to that spell's converted mana cost.
These are those "chintzy knockoff inventions"
Durza warned you about.
