Well, most of the time fury seems to be a waste of pillz...
It can be quite useful in many situations:
You have a character with +X life per damage. Using fury means doing at least 4 damages and sometime even more (Kenny with +2 lifes per damage mean you'll get 6 more damages!).
If you apply lesson #2 "thinking in less than 4 rounds", fury is a good and quite unexpected way to reach your KO :)
Dont use fury at all if you really needs to win most of the forthcoming rounds. You better save thoses 3 pillz to get an attack advantage.
Using fury in the first turn is a bit risky. You're opening yourself for an all-out attack from the opponent if he saves his pillz.
If you don't have any damage reducers of any kind, then save some of those "fury pillz" to pull of a 4 round victory.
I think Shakra with 1 pill and fury (only 4pills) is nice for 8dmg :)
but only use this tactic if you can see that your opponent has a crappy low pwr throw away card,
then there is still a 10% chance he has guts and tries to beat you with Zatman :P,
but at the cost of only 4pills you can recover if he beats you because if he does he will use at least 4pills :) basically its an advanced bluff :)
I had made a similar comment earlier, that if you use Fury on a high power card with few pillz, you have a strong chance that your opponent will let it through.
I've used it in the past, it can work, but it's often a 30-50% chance... because of the opponent decision making.
All is rounding about opponents deck.If he have cards with small damage and you have card like is Kenny or for example Cassio Cr fury will always come welcome.And when fury is on cards like Kinjo,Lost Hog there's always ways to block that because they don't have high power to be candidate for KO for xp players.
Im a fury noob -- hehe my first day playing, but i do like 2 rounding people, or using fury on a high dmg card, so that any of my next cards can win.. even if i just bluff the rest (if they saved pillz)
Don't forget Kolos is now also capable of instant death. In fact, he doesn't even need to be with other Nightmares, unlike Kinjo and the other Fang Pi's. But being with other Nightmares means the Roots and GHEIST bonus can't stop his ability. And he has 7 power. Of course, this also means that he costs more than 20k.
One time I love using fury is a situation something like this:
The enemy has 5 health left.
I have a decent card (eg. Platoona) that can do 5 damage, and a decent amount of pillz (eg. 6).
The enemy plays a card that reduces damage by two, but is probably bluffing it without spending much pillz on it. When someone does this, it almost never occurs to them that I might be able to end the game there. Reducers give a false sense of security all the time.
Simply play fury and the game is over.
