Sja-anat, Unveiled

Whenever a player puts a nonenchantment, nonlegendary creature into play, any player may sacrifice an enchantment. If they do, they put a
token copy of that creature onto the battlefield
under their control, except its an enchantment in addition to it's other types.
Creatures you control cannot be blocked by enchantment creatures.
