We had an interesting situation come up in one of our games tonight. Sardonyx was Banished. We were wondering whether the controller's loss of life continued while Sardonyx was Banished. We played that the loss of life continued, but couldn't work out the rules on Banish to be 100% certain. That's what it looks like in the Rules and Codex... it says "abilities that look for things happening in play... still work." We are just hoping for confirmation from our esteemed colleagues on this one.
We also got to wondering whether the controller of Sardonyx could voluntarily not lose life and remove Sardonyx from play, similar to a creature with an Essence Drain (for example) on it when upkeep is not paid. We are pretty sure that this is not the case, but also wanted to ask.
While on the topic of Banish, we also wondered whether hidden Enchantments on a Banished creature may be revealed. I don't think I can find anything on that anywhere.
Thanks in advance for your thoughts.
