While in a bt3 discord I was in someone brought up the fact that goku's give me your energy can ability can result in a spirit bomb dealing 50k damage if done twice. It sounds like a really good option in terms of beating the ai. At the same, give me your energy requires 2 blast stocks, and to get the huge damage would require 4 plus the additional blast stock needed to activate the super attack. The damage boost is needed but at the same time, the move has one of the longest animations in mid-goku's move list.

Yep, this strategy has even been explored in the fight against Burter and Freeza, if I'm not mistaken
