The engine

Mana Spell is server-authoritative: the rules run on the table, not in your head. Triggered abilities go on the stack in the right order, priority passes around the pod, state-based actions clean up after every action, and the commander tax is charged without anyone counting.

Card behaviour is written per card. About 30,900 of 31,000 Oracle cards carry rules today, 16,000 of them verified by tests, and every one of the 367 official keywords has a status you can check before you sleeve it.
