I used to play a ping deck similar to this but without Niv-Mizzet and his damage for drawing ability.
Ah, then you missed out on the nearly auto-win condition. Niv-Mizzet with Curiousity. Draw a card, then deal a point of damage, then draw a card, then deal a point, draw a card, and so on.
It might be a good thing to pick up more than one ensnaring bridge since a simple naturalize (or similar) will destroy your only real defense other than using your pings on creatures.
Scroll down the article. I'm aiming to build version 6. My Thieving Magpies and Quicksilver Daggers came in the mail today.
The game I assume is much faster now than it used to be, so this will probably get beat up on quite a bit. But it can't be any worse than tonight's draft. That was just brutal.
I was considering
Think Twice would be good, and the Flashback ability really changes this deck's potential. I just shouldn't have any trouble drawing cards, and I'm not sure what I'd even remove. The deck looks fine as is.
