By sacrificing a card in your hand, a card with this ability may attack more than once.
(Can be really useful, yet highly predictable.)
Piercing Strike :
A card with this ability ignores damage reduction, and may bypass a Protection based ability or bonus.
(This ability shouldn't be given to 8 damage cards, for obvious reasons.)
Last Stand :
This ability can only be activated if the card with this ability is still active in the fourth round. A card with thiz ability may ignore power, damage, and attack reduction, bypass Protection based abilities or bonuses, and may activate fury with no cost.
(Really, really OP when used with a Pussycats
half deck, MUST ONLY be given to 5* cards.)
Or maybe it's time to introduce character specific abilities?
As long as this card remains active in a match, reduce all your opponent's cards' damage by 1, with a minimum of 0 at the start of each round.
(Will look good in a Cockatrice or Basilisk card. Nightmare
Maybe Last Stand should be a character specific ability... For a Montana
card called Tony!
