• standard cost: 2
• Value neutral: not really
• While not exclusive to red, is primarily given to red balloons and is basically their signature

Strength+X basically makes it so a balloon swings for much higher than their current size, and even when attacked they can still punch over balloons of the same size without Strength+X. it's a humble ability with a lot of use cases, and is particularly great for tempo.

Most of the time, balloons have Strength+2 with larger ones having Strength+3. Strength+X is also often given as a boost effect from card effects.
