Let's have a Cubic Duel, with Dimension Summoning. Our spirit energy let us control the ATK and DEF of our monster! You may normal summon monsters with a higher star count than 4, but the more stars the harder is to fill their ATK & DEF. Using a 4 star 2000 ATK monster will take 100% of your power, while summoning a 8 start monster will take 200% of your willpower to even reach 2000! Remember, using all of your willpower in a single monster will cause burnout!
