Harrist: Campaigns for Arkham Horror: The Card Game tend to be pretty self-contained, so for new players, there's very little to catch up on
Magic 2012 (2011) Magic 2012 was the last hurrah for Doom Blade and Deathmark, Black removal got quite a facelift with the newest turn of the Core Set
There are other rare abilities that come close like Absolute Virtue or Crystal Barricade
Just watch out for certain Exile spells like Swords to Plowshares or Vraskas Contempt that would make recasting Optimus more expensive (the Commander tax applies to both sides), or other annoying blue cards like Capture Sphere that doesnt kill him but does prevent attacking and blocking
Also remember that, although mulligans happen before the game has started, there is precedent for cards that have effects relating to it
Later print runs added numbering and shifted to green-backed designs, making the original blue-backed variants prized relics of Pokmons collectible origins
