When Ajani's Aid enters the battlefield, you may search your library and/or graveyard for a card named Ajani, Valiant Protector, reveal it, and put it into your hand
Another thing to note thats more trivial than anything is that there seems to be no oversized Commanders within the product, which has also been a mainstay of the deck for as long as it's been around
The same is also true of any other abilities that modify how a land enters the battlefield or apply "as" a land enters the battlefield, such as the first ability of Cavern of Souls
Being able to switch power and toughness also means this card can work well on offense and defense
This might be one of the best rituals you have access to for Commander and it's capable of some very disgusting turns
Looking back, the block is a cautionary tale where we leaned into a typal theme but didn't account for the lessons we had learned
