I read somewhere that Jayemdae Tome, Jalum Tome and Emmessi Tome were named for people. Gavin's blog revealed that the first was named for James Michael Davis, but for whom were the other two named?

Jalum Tome or J.L.M. Tome is named after Joel L. Mick who was both Head Designer/Developer (when it was one position) and Magic Brand Manager at different times. Emmissi Tome or M.S.E. Tome is named after Mike S. Elliott. Mike was a prolific designer that lead the design of more Magic sets than everyone who doesn’t have their own Blogatog.

you recently said on twitter that Jayemdae Tome was named after someone (a high level employee of WotC, if I'm not wrong) and that one of the "mares" was named after someone's late wife. Is Emmessi Tome (M-S-C) named after someone else in particular? Are there any other cards named after real people?

Emmessi Tome (M.S.E. Tome) is named after Mike Scott Elliott, one of the most prolific Magic designers to ever grace the game. The only person to have led more design teams than Mike is me. Mike was on the Tempest design team, the set with Emmessi Tome. Jayemdae Tome (J.M.D. Tome) was named after J. Michael Davis, the partner with Richard Garfield that first came to pitch Roborally to Wizards of the Coast which led to Peter Adkison asking Richard for the game that ended up being Magic.
