The Flim Flam Brothers

Our Original Design! — When The Flim Flam Brothers enters the battlefield, return target
artifact from an opponents graveyard with mana
value 4 or less to the battlefield under your
control. Create 2 Treasure tokens.
Study The Competiton — Whenever an opponent
casts an artifact spell, you may copy that spell.
You may spend mana as though it were mana of
any color to cast that spell.
