Strength gives the ability to add 2 attack to a monster and is a Bravery deck specific card. It has been reworked multiple times in order to try and balance out the win rate of Bravery. Originally it cost 2g and added 3atk before being cheapened to 1g during Beta 2.0 to buff Bravery when it was considered weaker. After an increased win rate for the soul type and multiple changes to other Bravery cards, strength was changed back to costing 2g in Beta 4.1 in order to nerf the deck. During Beta 4.2 it was reworked to costing 1g but giving 2atk instead of 3 as the Beta 4.1 update didn't seem to fix the problem. After Beta 4.8 strength had its effects and cost reverted to that of the Beta 2.0 update.
