EX-4 Broly 2,500,000 rising damage?

with your current team you cannot do anything. You need a 2000 lvl Ssj goku blue in a mono blue team with trunks (legends road) who can create a special move and if you can blue android 18. with these 3 characters who can create a special move each the tactic is
1: collect all dragon balls and unlock rising rush
2: try to find a special move
3: use their main ability to draw other 3 specials (ssj blue goku last)
4: land the first special with ssj blue goku
5: rising rush using a card which isn't a special move and then you will inflict a massive damage
this happens because blueku's first special will increase the special move damage by 50% and his main ability, which draws the special move, boosts the special damage against character Broly
sorry if I couldn't help you
