mtg nightmare cards The Mindskinner Altered Full Art Duskmourn Mill Commander All cards will be carefully packed for safe transit Nightmare | 5th Edition |

So using a card from your hand as a resource is clearly not a new mechanic

This seems like an incredibly fun Eldrazi commander that can turn all your Spawns and Scions into 9/9 beaters

If all of the spell's targets are illegal when the spell tries to resolve, it won't resolve and none of its effects will happen, including those from cards spliced onto it

With Ranar the Ever-Watchful as your Commander , you can create flying spirit tokens whenever you foretell or exile a card, steadily building board presence

This means that in Commander you can only have one of these reskinned cards or its original print and cannot have both since they are functionally the same card
