Transformers cards are coming to Magic: The Gathering They'll be double-sided
It has lots of good (and expensive!) cards, so you may open a lot of value even if you only find a regular card
When your nontoken dorks die, a target opponent forces you to either draw a card or drop an equal or lower toughness dork to the battlefield, therefore making this a powerful machine for sacrificing for benefits in Esper rather than the normal home of Orzhov or Golgari
A unique version of the One Ring card fetched bounty worth a cool $2 million earlier this year
And it works well because its in the color of mana acceleration, and dropping all of those goodies for 4 mana a pop is pretty keen and cool
Its easy to turn it into a combo pieceit wins on turn 1 with Underworld Breach and Brain Freeze, generates infinite mana with Auriok Salvagers, and so on
