Imprint — When Soul Foundry enters the battlefield, you may exile a creature card from your hand.
{X}, {T}: Create a token that's a copy of the exiled card. X is the mana value of that card.
Most creature tokens have no mana cost and a converted mana cost of 0, but a creature token put onto the battlefield by Soul Foundry has the same mana cost and converted mana cost as the card it copies.
Soul Foundry puts a token copy of the imprinted card onto the battlefield. The token is put onto the battlefield, not cast.
The token is an exact copy in every way, except that it’s a token, not a card.
You do not get a chance to pay any optional costs, such as Kicker, on the imprinted card.
