Spark Reignition

As an additional cost to cast this spell, exile X
cards from your hand.
Until end of turn, you may cast spells from exile
without paying their mana costs. For each spell
cast this way that wasn't exiled from your hand,
you lose 10 life.
Each player exiles all Jace planeswalkers they
control.
Draw a card.
"Jace thought he could bring back his spark, but he
was wrong." - Teferi, Master of Time
