>>33271728the team I used for Groudon was a lvl3 mega Glalie, lvl10 Sceptile, lvl6 Kyogre and lvl5 a-grenigger (unity power lvl4) and managed to beat him both times I played by a good margin, chose to great ball so I wouldn't waste more hearts on it
the stage is not that hard, be sure to start by making a match on the 3rd, 4th and 5th collumns (one of these two lines, it's not always possible on the first turn)
