Interestingly enough, many of the cards removed from the base set for the Fourth Edition were removed for same reasons as many cards were cut from Unlimited (although some were brought back in later sets)
In many cases, this makes it a much better card
Go-wide decks can supercharge March of the Multitudes, after which they presumably have ways to take advantage of a pile of 1/1 lifelinkers
That's an even bigger sign, so no one wants to encourage the rest of the table to attack them for cards
Cheatyface can be snuck in at any time, while the Armchair is limited to your turn, but both must be in your hand to work
With decent stats, shes key to slowing down your opponent, and can be a good target for Ready effects
