Unfortunately, Im not at all familiar with the Fallout video games, so I cant judge these on flavor, but I do love me some awesome cards for my Commander decks
Though its most famous as Sephiroths sword of choice in VII, the Masamune actually appears in nearly every game in the series
I just think Rydia's Return is overcosted and not good enough, though it does seem good out of the sideboard for slower matchups
In artifact-heavy builds it might find Senseis Divining Top or Skullclamp
The art continues in the modern Magic tradition of showing definitive events and creatures in gorgeous full colour, and individual cards even tell their own little stories
Ripping free spells off the top of your deck is always fun in commander, and the ruinous powers deck comes stacked with them
