I'm not quite understanding how the REG talks about I/D.
For example, does Gibeonite Trickery mean that the 0/4 increase on the heroes last permanently (while they remain in play), or just until the end of the battle phase? Also, does Plagued with Diseases (when played as an artifact) continually affect my opponents' heroes while those heroes remain in play, or does it last until the end of the phase? What about when it's played as an enh? It's decrease is a one time deal and lasts until the end of phase?
The whole on-going and instant, statically and dynamically wording for I/D is what confuses me. In reading that on-going lasts until the end of phase and instant is permanent seems backwards to me.
