[Boomer17]

No I block the guttersnipe with my corpsejack leaving me at 2 life my turn

I'm pretty sure that's game. I'm swinging with everything, you can only block one 2/2, with 6 seeping through. GG

[Boomer17]

My turn untap draw tap swamp forest and rogues passage play {varolz, the scar-striped}
Still my turn what do u have untapped land and creature wise?

[Boomer17]

Yep my life was t six sorry I have my kid right now too putting him down GG

[lotrwk]

I already won.. I swung with 2 2/2's and a 4/4 flying. You were tapped out and had a corpse jack menace out. You could only block one 2/2, leaving a 4/4 and a 2/2 to go through and deal a lethal 6 damage.

It is game you are correct,even if he had creatures it wouldn't have mattered, you played sleep making them not untap

Edit: sorry again for interrupting I'm just trying to help

 It's alright. Your help was useful, pointing things out that neither of us saw. Thank you.
