Start by locating the Java card implementations or entry points for Bladin and Century Herdmaster in the Forge repository. Compare their intended mechanics with nearby card support and use the reported Moxgate scenario to verify that the AI can use both cards; done means both cards’ mechanics work and no longer make the AI unusable.
