There are a lot of things to like about Daniela. First, she lets you play tank guardian in a way no one else but Tommy can really master. But I don’t think she’s the second coming of Tommy, I think she’s the blue/red answer to Trish.
Previously, the number one way to lock down bosses was to have Trish Scarborough use quick clue gathering to automatically evade them. And she’s still super effective at that! But her ability is limited to once per turn, and Daniela's is not. Plus, as a cluever, you might have Trish elsewhere while big enemies spawn.
And Ms Reyes has the same stumbling block that Agnes does: if you spam their powers, you will get burned by the encounter deck. Neither is particularly great at agility checks, and damage can come from locations as well as foes. Often, punching enemies first is a better option than reflexively letting them clobber you, especially without access to money-makers like "I’ve had worse".
Her 4 base will is solid, even on hard.
Daniela is an excellent partner to Aquinnah. And if you’re willing to exile cherished keepsakes and old leather coats, the sky is the limit for soak with solemn vow. But when it comes to damage, observe the Christmas rule: it’s better to give than to receive.
Edit: Having played with her a little more, her ideal events are super cheap. That cost curve, and waiting for enemies to spawn, means it’s possible to put out a guard dog (or two!), flesh ward, and a survival knife before enemies cover the board. It’s refreshing in a guardian to be able to engage enemies as a final action, knowing you’re going to do 2-4 damage during the enemy phase! Annoyingly, there’s little lvl 1-5 survivor tech that does what dogs, “Get behind me” or the hallowed mirror do. And there’s not a ton you can do about enemies that do something besides damage/ horror on a hit: if you want to assign damage to your Trusted hounds, you can’t use dodge.
