It has the non-swamp restriction though, but thats mostly irrelevant if Urborg, Tomb of Yawgmoth isnt around
This is a very powerful 2-for-1, and while it isn't always going to be online, it won't be too difficult to get it there either
This isn't a big deal if we're grabbing a lot of cheap mana value creatures and planeswalkers or if we have a lifegain strategy with our deck
The average signature makes a card less valuable
Soulbond is a very odd mechanic, and one that hasn't been returned to much since it was first printed in the original Innistrad block, but Deadeye Navigator is probably the most iconic of the cards with the mechanic due to the ability to go infinite with some pretty innocent looking cards (plus Dockside Extortionist, but we dont need to worry about that one in Commander anymore!)
Again with the whole idea of playing proactive cards Recurring Nightmare was kind of sweet and I came to experiment with it a bit going forward
