I think the cards that come with hybrids should look like the pet but has everything like the original spell for example Helephant + Wraith = Death Oni The Spell when casted will look like a Death Oni but it will still be fire and do the same damage as Helephant Or Ice Colossus + Helephant = Inferno Colossus The spell when casted will look like a Fire Collosus (Like the one enemies cast) but will do the Same damage and be a Ice attack just like the spell Ice Collosus
We already have mutations like this, and Kingsisle would have to go through ALL of the pets and change all of the cards just to satisfy this idea. It's creative, but it's too much work. And what's the point? To just have a cooler looking spell? I think the crafted/pack spells are a REALLY good idea. I'm working on Samoorai right now!
