I don't have a problem sending first if you have a good amount of positive feedback.

I mostly play Modern with some Standard and as such mostly trade for those staples.  I don't generally like to trade down, if I'm going to, I expect to get some major value in my favor.  I will always offer the same courtesy in my trades.

I use TCGplayer.com low price.

I ship in penny sleeves+ top-loaders.  For trades over $25 there will be tracking and I will reinforce the top-loader with cardboard.  I ask people I trade with to treat their shipments to me with similar quality.

I collect Vizzerdrix/Trained Orgg and this foil Island from Odyssey (http://store.tcgplayer.com/magic/odyssey/island-(338))  If you would throw any of those that you have in, it would be awesome!

I look forward to trading with you!
