they reveal as written. This way a dodge and a glancing blow can be used In tandem. I believe. Not in front of the cards right now. Regardless of the second part of the answer, they reveal during declare attack as written.

You know you wanna play a siren. You just know.

 oddly poignant here sailor.

4 heals and 6 minor heals is an insane over commitment. Not only is heal your full channel in one round, but it's not seem feasible to play both in obe round on base channel. Not even on massively increased channel. The only one who should do anything close to this is a resto pally that is counting on healing for gaining his valor. And even that is a stretch. One mage wand offsets the need for 2 copies of a spell. Plus even In school that's 14 sp you're not using for anything else. Not the best idea

Yes they are.

 The merren would only take 1 damage. This is calculated after armor. The snatch is actuallt strange and 2 things could happen
1. You would snatch the knight of the red helm toword you in either case.
A. The knight of the red helm is in your zone now. Then the merren takes one damage and a snatch from eye for eye... amd gets moved nowhere cuz it can't go closer to a thing in its zone already.
B... now that i think about it there's no b. That's what happens. The only confusion here is whether the hypothetical useless snatch would (hypothetically) snatch you toword yourself (cuz you're the source of the attack and it would then do nothing), or the knight.
I suspect the former.

I don't even know if you can put the marker on an invisible creature. Does it require targeting? But yes even with chant of rage they can completely ignore a  invisible creature for all intents and puroses. So itd be a bad choice

She was indeed.
