Interested in some statistics based on MTGO replays? MTGGoldfish has you covered. for every draft format they do a breakdown detailing various statistics of limited matches, and their stats for Dragons/Dragons/Fate can be found here.

Just looking at the top commons, you can see that there is some bias in the reporting. Replays don't let you see cards in players hands, so if a player loses with a specific card in their hand it doesn't impact the card's record. Naturally, we see some artificial inflation in the win percentage of Magmatic Chasm.

I think the most interesting stats here are looking at play versus draw. This is always an interesting question for me in draft formats. I'm generally biased towards drawing, though I've chosen to play for every iteration of Khans block limited. The stats here show the win ratio of play draw being razor close around 50%, with players mulligaining winning a considerably high percentage of games when they're on the draw. Interesting food for thought.
