Mardu is black red white I think... sooooo .... white! I did it!

Had the game freeze during attack phase. I was swinging in with a few creatures and exerted a Gust Walker, my opponent stopped the timer and went to activate his Smugglers Copter. Game froze for a few min then opponent disconnected.

Haunted Dead has been causing me headaches. If you use the ability from the graveyard by using the alternative-view of your graveyard for special ability cards in there, if you minimize the hand to try and see what's going on with you mana or board state, you won't be able to get back to your hand to choose the cards. luckily (or unluckily depending how you see it) the game will automatically choose two cards randomly to do the ability, you can't avoid it once this has happened.

it's pretty annoying, i'm pretty sure what's causing the glitch is the interaction of haunted dead with the alternative-view of your graveyard.

This is WotC reading this right now

I think Glyph Keeper is broken. I've targeted one with a Galvanic Bombardment, hoping hit him with another, but the first one actually hit. This was shortly after I targeted him with a Baral's Expertise which worked.

Also, I counted that Sphinx's Tutelage is acting weird, too. I had two of them in play, then drew two cards. The opponent then trashed 2, 4, 2, 2 cards.
