Andromeda of the Cosmos

{w}{u}: Until end of turn, Andromeda becomes
an enchantment and loses all other card types.
As long as Andromeda is an enchantment,
creatures your opponents control attack you each
combat unless their controller pays {1} for each
of those creatures.
{2}{b}: Exile target creature that's attacking you.
Activate only if Andromeda is an
enchantment.
