I begin telling you that i'm sorry for my english, but i'm italian, and... Italy isn't the best place to learn English XD
I agree with the idea to use the
Blightning, i really love this card! For the
Duress i already play with 3x, and a
Despise's 2x, that i think it's simply useful. Obviously
Thoughtseize or
Inquisition of Kozilek is the best choice, but the alternative is represented by
Duress and
Despise (or
Distress, but with double B cost).
I had difficults with the choice of the lands, but the
Savage Lands aren't probably the best on mtg XD But at the moment I don't know how to replace them. Could you help me?
Probably a bad situation is represented by the lack of mass removal (even like
Pyroclasm, or similar). Probably i should use
Anger of the Gods, but I really love
Blightning, indeed i'll replace the "Destroy a land" with
Blightning (even if the "destroy a land" effect is really a good control choice. Probably i'll put them in the sideboard).
Thanks a lot for the comment, see you soon!
