Thanks philato but my priority now is for Yawgmoth's Will  :lol:

Thanks for your comment, i will try to find a Nantuko shades and for the Nevinyrral's Disk, i think he could play anyting with my nether void or gloom etc.. so it's ok  :lol: and yes Hell dozer is better but.. i don't like this new desing on new cards  ( Mirrodin an up.. )
