This card shouldn't be allowed in PvP at all to many are trying this trick so keep spamming it enough and many will complain and it will ended up being banned from PvP to.
Really? Beguile? Yet I don't hear you complaining about GS or Jade gear. In my opinion those need to be restricted somewhat. Beguile offers a great strategy for Necromancers who actually use it. Not many do you'd be surprised how few of them I run into.
buguile is an awesome spell for pvp my favorite trick it does is when it switches your health around. i mean that is confusing i am scared to kill the oponent when i cast because i am afraid i might kill myself rofl. (Blaze Moonmender promethean)
if you know your facing a death you can just use a single hit spell on him and kill him if your already hit by beguile you can pass the first turn then cast an aoe the second turn so long as your ok with hitting a teammate or 2 depending on who the target was originally since it ends on their turn.
