Minor Adjustment

Strategy
Minor Adjustment either gives a unit +1/+1, or -1/-1. This means it could be used like Flare to get rid of a 1-HP unit, to nullify the fact a 1-ATK unit has Deadly, before using a unit with Duelist, enabeling it to survive a trade it'd otherwise die in, or just to give a unit +/- 1/1. It's not that strong, but makes up for it in flexibility.
