Corruption of Towashi Foil

Enchantment

When this enchantment enters, incubate 4. (Create an Incubator token with four +1/+1 counters on it and ": Transform this token." It transforms into a 0/0 Phyrexian artifact creature.) Whenever a permanent you control transforms or a permanent you control enters transformed, you may draw a card. Do this only once each turn.
