W: Cards to finish modern grixis delver. H: stuff from modern infect

I dont need a whole lot more.. i have all the expensive stuff that im willing to pick up right now... waiting on tarns.
Needing stuff like electrolyze, tasigur, 1 strand, etc....

Im trading my modern u/g infect for it.. i have traded off quite a bit but still have some piece, along with a few random legacy infect pieces and whatnot...I have some windswept heaths and wooded foothills id probably be willing to part with if i had to. 

Everything is in my wish and tradelist thanks.
