What are some fun decks to pair runick with?

I got bought a box of tactical masters over christmas and managed to pick up most of a runick engine and I'm thinking about getting the singles I'm missing.

Initially I thought about generaider or melffy but there are some parts of the generaider deck that seemed weirdly expensive and the melffy deck I saw was in MD so idk how well it transfers over to TCG so I thought I'd ask here for alternatives.

My biggest concern is cost I'm not that fussed if the deck is that good since i'm only taking it to locals for a bit of fun.
