msem-instigator

Exile target creature. If you controlled that creature, create a 4/4 red Dragon creature token with flying. Otherwise, its controller creates a 1/1 white Bird creature token with flying.
Showcase {4}{U} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)
