Sphinx of the Guildpact 7
Artifact Creature - Sphinx
Sphinx of the Guildpact is all colors.
Flying
Hexproof from monocolored (This creature can't be the target of monocolored spells or abilities your opponents control.)
5/5
Might just be off the mark here, but is this shops playable? The 6 spot gives us Wurmcoil and Hellkite, and 7 is just a lot of mana in general. However, this blanks plow, by force, grudge, bounce spells, etc., etc. A 5/5 flyer for 7 isn't super hot, but a 5/5 flyer on the battlefield is better than a 6/6 wurm in exile or a 5/5 hellkite in the graveyard.
