Yeah, I played Mindbreak Trap for its full cost yesterday! Yay!

...You did? How? It's not out yet.

I meant Whiplash Trap. My bust.

Ahhh, that makes more sense. Did you shout "IT'S A TRAP!"?

can you sacrifice an indestructible creature?

Yes

It didn't come up today, but I'm going to guess that the limit break on the black planeswalker lets them see your hand and any other secret information you have access to for the purposes of controlling their turn. Is this correct?

I'm wondering how Mind Slaver effects work when you have cards that you can see but no one else can from outside of the game (like cards removed with Jester's Scepter).

They can see your hand, I know that for sure. I would assume that they can only look at cards you removed from game if you could do it on your own but dont quote me on that.

The Mirrodin FAQ entry for Mindslaver says plainly that you can see everything the controlled player can see, which includes things that they're allowed to peek at but nobody else can.

With Punishing Fire, the new recurring burn spell, does it trigger over and over again for each instance of life gain? Or does the trigger just see life gain in one instance and just pop back once?

Could you ask the question in a slightly different way to clarify?

Not positive what you're asking. Here's a hypothetical situation that might help. Say you have a Punishing Fire in your graveyard, and your opponent has a soul warden. Every time a creature comes into play, you have the option of paying R to return Punishing fire to your hand upon resolution of the soul warden's ability. If someone puts multiple creatures into play at once (IE, spectral procession), the soul warden's ability triggers three times. So you can return it from your graveyard to your hand after the ability triggers once, cast it, return it again after the ability triggers a second time, cast it if you so choose, and return it once again after the ability triggers for the third time. You can also just not activate the ability at all, and still do it.

And obviously, if the card isn't in the graveyard, the ability doesn't trigger.

*Hopefully* that helps.

Ok, there we go. That's what I was wondering.

If my opponent casts and activates Planeswalker's Mirth, is putting in a monocle and making the face that Urza is making on the card an optional action or is it a required action, if and only if there is a monocle within arms length?

The question is invalid because the Planeswalker in the art is Commodore Guff.
