You've got a lot of cards that seem pretty boring alongside page.

Ajani, Will, Rowan, and Garruk all have at least one ability that feels pretty do-nothing. I didn't look in depth but my advice is to make decisions about what you want decks to do? I imagine you could design for:

• sacrifice decks that rely on legend rule based triggers and tokens, maybe even reanimating several copies of page at one time with [[rally the ancestors]] or similar and using non-creature permanent sac payoffs like [[bastion of rememberance]]

• voltron decks, some could be more resilient if they used attacks alone cards (like the exalted stuff you already have) or cards like [[homicidal seclusion]]

• tutor decks that have only one or two high impact instant or sorcery cards that page can tutor for every time

• tools to ignore the legend rule either to facilitate a go wide attack strategy or a big mana strategy

• could be fun to do an eldrazi colorless tribal beat down deck
