Proft's Eidetic Memory A draw payoff that also draws you a card is pretty cool
It's easy to trigger it yourself as well, as Ledger Shredder is most commonly played in decks that run a lot of cantrips (one mana spells that replace themselves in the hand when cast by drawing)
Its not unreasonable to think you might just draw twenty cards, right there, and if your deck contains a very unusual amount of mana, you might not be far from drawing your whole deck (especially if youve got a couple of Dakmor Salvages somewhere in the mix, making it completely deterministic that you mill your deck, fill the battlefield, and set up some graveyard kill)
Ultimately, Alela, Artful Provocateur is still a fantastic choice to helm a Faerie Typal Commander deck
Commander rules get in the way of both her ninjutsu (which cant be activated from the command zone) and her reanimation trigger (since your enemys best creature wont stay in their graveyard)
