Eldrazi at SCG Philly

[btm10]

This is a topic that's come up indirectly in several deck threads and explicitly in several conversations I've had since the weekend, so a centralized thread seems appropriate. What overall metagame penetration do people expect Eldrazi (all variants) to have at SCG Philly? My personal guess is that it's going to be about 10% of the day 1 field and hold that number into Day 2, largely due to some of the pilots being Modern players who bought 4 Ancient Tombs and aren't familiar enough with Legacy to play the port optimally. I definitely expect to see at least one copy in the top 8, and at least one more in the top 32.
