One of the most fun decks to build in Magic: The Gatherings Commander format is a group hug deck
Mixed with the right creatures, it can be the heart of a powerful combo deck: Yawgmoth, Thran Physician, plus two undying creatures (for example Geralfs Messenger and Young Wolf) generates a Yawgmoths Bargain sort-of engine, that can be turned to a One Turn Kill adding a Zulaport Cutthroat effect to the mix
The Seventh Doctor card, showing Slyvester McCoy as the Doctor, features a much more complicated ability that has defending players attempting to guess whether the mana value of a card in the attacking players hand is greater than the number of artifacts they control
Having access to a one-mana way to recur my six-mana commander was invaluable, and helped the deck function as a Voltron deck a lot better
these will be numbered and in very limited quantities
Get creative and these artificers can take your artifact game up a level
