What Are the Must-Buy Cards for Ira? Building a Deck for RTN

Hii! After one of my posts asking for advice on what deck to get, I became really interested in Ira. Her gameplay feels like a mix of Guardian and Ninja, which really clicks with me.

What are the must-have cards for her? I already have Sink Belows, Fate Foreseens, and most of the Ninja core deck (I’m thinking about getting Red Bittering Thorns).

I’m trying to keep my deck kind budget, but I’d appreciate any advice on more expensive cards too.
