That one is quite simple.
As you know, you get a "sureshot" if you have twice or more the attack of your opponent.
Hence, in a round with 2 cards with equals powers, if you put one pillz when your opponent doesnt put anything: you get a sureshot At the cost of only 1 pillz, it's worth it, no?
This one pillz can be very powerfull
I'm not going to complain... really. I'm not positive on the math, but if my quick math was right, I SHOULD have gotten a Sure Shot (a few times!), and have still lost... and, on the other side of that, I've been POSITIVE my opponent had sure shot (since I bought his bluff and had no pillz... oops), and I won... which gave me the game. Don't get me wrong, I like the win, since it was a T1 game, but it sucks when you're sure you have it, only to have it snatched away by.... ? My question would be, just to confirm my own idea, what things should I look for? I know bonuses, support attack, atk+ cards, Hugo, etc... is there anything non-obvious that could alter the math?
