The Horn

Haste, trample
At the beginning of each combat, choose one —
• The Horn becomes a 6/4 blue, black, and red
Demon Shapeshifter with haste and trample
named The Horn. It keeps this ability.
• The Horn becomes a copy of target creature or
target creature card in a graveyard, except its
name is still The Horn, it's still legendary, and it
has this ability.
