Alyssa's Star Challenge

When Alyssa's Star Challenge enters the battlefield, you become the monarch.
At the beginning of your upkeep,
choose up to one other target enchantment or artifact.
If you're the monarch, you may create a token
that's a copy of it. If you're not the monarch,
you may have Alyssa's Star Challenge become a
copy of it, except it has this ability.
"Will you accept my offer?"—Alyssa
