Neel, Innovative Engineer

Whenever Neel, Innovative Engineer or an
artifact enters the battlefield under your control,
if you don't control a permanent with the same
name, you get {e}.
{t}: Discard up two 2 cards, then draw that many
cards. For each artifact card discarded this way,
you may pay {e} equal to its mana value. When
you do, cast it without paying its mana cost.
Kaladesh's richest fight over his scraps.
