Forum:Confusion with The Wicked Dreadroot vs other effects

I just have a few problems when it comes to The Wicked Dreadroots rulings. First: Does The Wicked Eraser get affected by the dreadroot, and if it is, is its ruling like the OCG ruling for Dreadroot vs. Avatar. Two: On my copy of Tag Force 5, I had summoned Dreadroot and hit my opponent directly, then he summoned Tragoedha by its own effect. Tragoedia wasn't effected by Dreadroots halving effect. I do run a Wicked God deck, so i will be editing this post if future problems arise. Thanks for the help.
