Slay the Spire 2 Ironclad Card Tier List

This Slay the Spire 2 Ironclad card tier list ranks the 76 Ironclad cards with enough recorded data by their win rate when played as the Ironclad, sorting them into S, B, C, D and F tiers. Unlike the all-classes ranking, every placement here is based on how each card performs specifically in Ironclad runs — so a card that is only average overall can be a top Ironclad pick. Tiers use the same percentile method as the rest of the site: the top 15% of cards by Ironclad win rate land in S, the next 15% in B, and so on down to F. Right now the strongest Ironclad cards — the S tier — are led by Forgotten Ritual, Metamorphosis, Feel No Pain, with Forgotten Ritual posting the highest Ironclad win rate at 66.7%. Use it to prioritise your card rewards on a Ironclad run, build around the cards that actually win for the class, and skip the low-tier picks. Win rates update as more Ironclad runs are recorded.
