Riddlesmith

I had one Repeal, one Pirite Spellbomb, one Brainstone.

I did end up with Riddlesmith, but with almost no artifact cards to trigger it, so I'm not even really gonna count that for Irencrag Pyromancer.

I had Tirsa, Lights Shatter, Jori En, Ruin Diver, and that's it.

That was it in terms of ways to trigger Irencrag Pyromancer.
