This is a good card for protection if you plan to not take damage for other card effects to proc. If you're planning to use Protection to just reduce incoming damage (e.g. Bishop WANTS to take damage) and someone else needs this card, I'd recommend Front Line Specialist instead.
Adding a link to Specialized Training because I keep needing to search it when I look up the specialist cards.
I'm including the other available specializations below in case you want to hop directly to the other cards:
- Combat Specialist (+1 ATK) [After basic attack → draw 1 card]
- Front Line Specialist (+4 HP) [After you take enemy attack damage → draw 1 card]
- Surveillance Specialist (+1 THW) [After basic thwart → draw 1 card]
