Card not found is a strictly better version of Card not found and is a common as well
For reference, the other five tokens in that Unglued group are the extremely common Red Goblin (29 sets, 14 unique art printings) and White Soldier (29 and 12), and the significantly less so Green Squirrel (4 and 4), White Pegasus (2 and 2), and Green Sheep (printed only the one time)
Being in mono-white means shell at most be a two-color deck with a background, but there are a ton of different directions you can go with Laezel and still play an energy-focused game
Mass Manipulation costs XX and four Blue mana
I count 29 cards that are either Phyrexian or make Phyrexians, plus 41 cards that either are artifacts, make artifacts (incubate tokens), or care about artifacts
