Terrific answer. Thanks!

I control an Ilharg, the Raze-Boar and attack with it, bringing in a Hellkite Charger from my hand. Do I get to use the Hellkite's activated ability? I'm not sure if there is a distinction between "attacks" and "put onto the battlefield attacking". It was not declared at attacker. Does that matter?

Rhadamanthus Thanks, that's what I thought. It came up in a playtest situation in a Krenko, Mob Boss commander deck. So big yes on that last part.

I control a Conspicuous Snoop and have a Kiki-Jiki, Mirror Breaker on top of my library. Can my Snoop make infinite token copies of itself (until the end step)?

wallisface Wow, I had guessed it would go the other way and check my creatures' P/T before the card draw. I suppose it does, but then the loss of buffness happens before the block is declared. So then I guess that means they lose flying before the block is declared as well.

I control a Vampire Nocturnus and a Preacher of the Schism and I have the most life. The top card of my deck is a black spell and beneath that is a Swamp.

I attack with all my creatures (Vampires). Do they get to keep the +2/+1 boost from the VN or do they lose it by way of my PotS topdecking my black spell and making the new top card be colorless?
