Something about the name Juggernaut suggests to me that this card should have momentum, moreover Juggernauts generally have relatively high health levels, maybe raise the health to 5, maybe 6, however with the current ability this would really have no purpose. Also, how would this card react to Area of Effect spells (ie pandemonium, plague, rain of fire, dryspell, thunderstorm) where the card isnt actually targeted? Would it cancel the entire spell, or have no effect?
