Enchantment — Aura
Enchant land
When this Aura enters, incubate 2. (Create an Incubator token with two +1/+1 counters on it and "
: Transform this token." It transforms into a 0/0 Phyrexian artifact creature.)
Whenever enchanted land is tapped for mana, its controller adds an additional one mana of any color.
