I agree that the fact that theyre just paper printouts with crude or pasted art works against them
Powerful counterspells like Mana Drain or Narsets Reversal, board clears like Perplexing Test or Evacuation, card filtering like Dig Through Time or Frantic Search, raw card draw through Blue Suns Zenith or Commanders Insight these only just scratch the surface of what a Merchants Scroll can do to reinforce your hand and available options
For the low cost of three mana, Shu Yun is a 3/2 with prowess, meaning its power and toughness increase until the end of the turn whenever its controller plays a noncreature spell
Alandra, Sky Dreamer rewards you for the latter, which is the one you want to do anyway
It was an important part of Tron decks, where people could cast it on turns 4-5 and slow down their opponents significantly while also putting a 7/10 in play
This helps with quickly ramping up the number of cards in your inkwell , making it easier to play the high cost characters like Belle, Mechanic Extraordinaire, who can also be a shift target , as well as Lyle Tiberius Rourke, Crystallized Mercenary, who is not only a key damage dealer , but also pretty darn good at questing
