Rionya, Fire Dancer

At the beginning of combat on your turn, create
X tokens that are copies of another target
creature you control, where X is one plus the
number of instant and sorcery spells you've cast
this turn. They gain haste. Exile them at the beginning of the next end step.
Once an innocent child from a destroyed village,
Rionya was the only survivor of this tragedy. Seeking refuge within Valakut, she harnessed magic to attempt
the impossible: recreating her lost loved ones.
