I enjoy providing a list of different perspectives, but without gaslighting about what is tried and true
Sire of Seven Deaths is a giant Eldrazi that helps you to stabilize your board, and it fits into every deck interested in playing a 7-drop, especially in colors that want to gain life and cant (, mostly)
second, the opportunity to cast spells for free for the rest of the game without depleting resources in hand
If that person laughed, the token gains haste until end of turn
If Journey to Nowhere leaves the battlefield before its first ability has resolved, its second ability will trigger and do nothing
The best case for all of these cards is probably Edric, Spymaster of Trest, which held steady at around $4 with very fringe legacy play, until it ended up winning a SCG open last April and spiked to $15 overnight (before getting reprinted in Conspiracy a few months later and dropping dramatically)
