What you need– A Pyrus/Subterra bakugan (any gpower is fine)A decent bakugan in the attribute that's highest on its gateAnd your leonidasA card that uses the attribute triangles (Aquos, Pyrus and Haos Combo or Ventus, Subterra, and Darkus combo)A 'prevention' cardand any red card (I prefer a battle re-do card that changes the minigame)A gold gate that matches one of your bakugan (NOT The ST or Pyrus)Any silverAny CopperFor the example, well use...Darkus Leo 670Subterra Manion 550Ventus Ravenoid 550PreventionTiming Battle Re-doST, Ventus, and Darkus comboLeonidas[insert silver card here, to lazy to check]Down For the countTurn one, set the gate for Leonidas. Roll your Leo on your gate (if there are any Max S.Power coins, be sure to pick one up). Make sure the opponent lands on their card.T2, use the ST or pyrus Special throw, make sure to critical KO the opponent. Then, they land on your card with whatever they use. (unless, of course, they set a gate, then they'll go for that.) If they land on a different gate, then roll ravenoid onto it. If it's a minigame you're not good at, then change it with the re-do card. Let them activate the AC first, if they have one. If it gets dangerosly close to the end, activate the ability. If the battle's on your Gold gate, play prevention. So, you SHOULD be at two gates by now. Set 'down for the count' and roll a Sub-terra onto it. The opponent will be unable to play abilities while you can stll do so, unless they're Sub-terra as well. Activate the Combo card you're using and beat the 'infinity sign' minigame. You should have won by now.If not, then... Well, do whatever you can to win. Good luck~
