First chapter is a solid removal spell, while the others give you an extra card from the top of your library, and it ends with 6 free mana
With the chance to have up to four copies of this card in your deck, its a fast way to accelerate your ink past your opponent, helping you to unleash more expensive cards earlier in the game - or simply flood your board with cheaper cards - to help take you to victory
For example, if you control Johann, Apprentice Sorcerer ("Once each turn, you may cast an instant or sorcery spell from the top of your library.") and Questing Druid is on top of your library, you can cast Seek the Beast, but not Questing Druid
This combination of strategy, versatility, and surprise makes Faceless Menace a compelling choice for both casual and competitive MTG players
Maybe you've been told it doesn't work the way you want it to, because Inalla exiles copies at the beginning of the next end step, so even if you end your turn before the End Step, they'll just get exiled on the end step after that
You can look at the top card of your deck at any time, which is nice, but you can also play lands from the top of your library, which is even nicer
