To be honest, this entire last set is just horribly thought through especially in regards to how it synergizes with the SS3 Goku Lead. For example, while I may hate the Swap archetype, there is something to be said about how INSANELY overpowered it can be when you focus on JUST the low-cost units.
You can a very similar set-up to what you're offering there with The Legendary Flute, only I'd argue slightly stronger (although you trade out the Criticals).
Working from your basic set-up, you can use the SS3 Leader Skill. 2 Energy, 6 Life, -1 in hand, the same as your set-up.
Bring out Bardock, the Progenitor. +1 to hand. Swing at the enemy, swap out to Scrambling Assault, Son Goten.
Son Goten swings, you check top 3 and add a card to hand. Other two cards go to bottom of deck. Another +1 to hand total.
Resummon Bardock, another life to hand (+3 total).
Awaken SS3 Goku BEFORE swinging with Bardock again. Also swing with him if you don't have Goten. Draw 2 from Awaken, and 1 from attack (+6 total, I believe).
Swing with Bardock, swap out to another Goten (or a Dependable Dynasty, Son Goku in lieu of that, for the extra power).
Swing Goten for another + 1 (+7 total).
That's 5 swings at at least 10k turn 2, giving you a +7 in hand and 2 units left on the board who each give you a +1 when they swing.
Your opponent gets the pluses from their life, I will grant. But they're also only on 2 energy, and you still easily have the hand advantage. And if they didn't drop cards to stop at least SOME of your attacks, they are at a HUGE disadvantage. Regardless on if this is stronger than the Legendary Flute + Intensifying Power, Trunks combo or not is irrelevant, that is straight up unreasonable and unacceptable.
EDIT: AND LET'S NOT GO FORGETTING THAT YOU CAN RUN SUCCESSOR OF HOPE AT 4 AS WELL, AND SEARCH YOUR COMBO PIECES FOR LITERALLY NO ENERGY COST. BECAUSE THIS DECK NEEDED TO BE MORE CONSISTENT AND FASTER.
WHO THE FUCK CAME UP WITH THIS.
