Matti_Naesae, if you look at the bonus only I would tend to agree with you, but you need to consider cards themselves to see how the deck would work
consider C Wing
, play him at 0 pills, if he loses opponent get -2 life, you get 1 pill, then you lose health, now you have 3 turns to do 10 damage with 13 pills, sometimes this is easier than 12 damage with 12 pills.
Also, consider Deea
, at 16 and 19 attack at 0 pills, your opponent would need to pill to beat them at 0 pills, so they cause an even greater pill gap.
Most games don't end in a shut out, even 2-hit ko decks usually go to round 3 with a 0 pill card to save pills, Vortex
lets you use this strategy to a greater extent, definitely not a horrible bonus.
