This clever loop transforms Alena, Kessig Trapper into an artifact creature with the help of Liquimetal Coating, opening the door for Voltaic Construct to repeatedly untap her. Because Alena generates red mana based on the greatest power among creatures that entered the battlefield this turn, and the construct only requires a modest two-mana investment to untap her, you can cycle this activation infinitely. The result is an endless fountain of red mana to fuel the rest of your strategy.
