rooftop storm and risen executioner
Asked by abenz419 8 years ago
With Rooftop Storm in play can I cast Risen Executioner from my graveyard for 0 or does it not work because they are both alternate costs?

9/22/2011 You must still pay any mandatory additional costs, such as exiling a creature card from your graveyard for Makeshift Mauler.
So you can cast Risen Executioner for 0 plus the additional cost of 1 for each other creature in your graveyard.

Risen Executioner's last ability is not an alternate cost. It's just a static ability that allows you to cast Risen Executioner from an additional zone by paying an additional cost. Remember that additional costs are still applied if you use an alternate cost.
Casting cost = [mana/alternate cost] + [increased/additional costs] - [cost reductions]
Risen Executioner may be cast from your graveyard for
+ 
x (number of creature cards in your graveyard)
