If you cast mage blight, you will likely die.
Being safe, while being in 13.9" from the enemy caster is a recipe for unundeath.
Mage blight is only good when you are way ahead and is the salt in the would, rather than true denial, mainly due to the lack of shadowmancer and being a medium base.
At Lear that is my experience and of the games I have watched. I would call mageblight a trap spell.
I've had Mageblight work for me a few times, but I agree that it tends to be a trap to cast it. That said, it was glorious playing it against Carver in a mangled metal + a solo tourney. What? You didn't bring gunboars? Let me walk right up here and cast Mageblight, no feating for you! He backed up then and feated, but couldn't get them to Goreshade. Even if he could get them to Goreshade, if you block off the area directly between you, it makes it so that he'll have to go to the side and can't force his beasts . Anyways, Mageblight worked well in one specific situation.
So played 2 games with pShade last night (also noticed how pathetic he and deathwalker looked......my first miniatures i ever painted......so yeah terribad, so bought a new blister whilst i was at the games store) Tagging along with him was the kraken and Deathjack. In both games i popped my feat and used banes to either block charge lanes to me, or to open charge lanes for deathjack. My favorite was one turn, deathjack converted 4 souls to focus, and the kraken burned 3 corpes, so my 3 model battlegroup was using 16 focus......a fully loaded kraken and overloaded deathjack and i dropped mageblight so eSevvy couldn't retaliate (if he survived) after DJ charged him.......he obviously did not. My favorite part of this combo, is i kept DJ up in front of the kraken, and it forced my oponent to either focus ranged against the non-stealthed kraken, or charge into deathjack, and face kraken retaliation next turn. Shadowmancer works great for mindf***ing people.
