Evoke Evoke is like level up but generally in reverse, it allows you to have a really strong late game card that can be used to lesser effect when in the more important and more random early stages of the game
Being such a one off you basically need to win with it when you use it and this massively reduces the number of threats that are good with it compared to Sneak Attack
If a creature an opponent controls can't attack for some reason (such as being tapped or having come under its controller's control that turn), then it doesn't attack
Or you can play nice and only use the first activated ability
The card is just as despicable as he is, and its power suits him to his cold, cold core
Now there's nothing to fear from blockers, or fog effects, and you can kill everyone without connecting, at instant speed
