With the release of "Ronintoadin" from The Shining Darkness, "Frog"s gained the ability to perform a First Turn Kill which involved following key cards: "Substitoad", "Swap Frog", "Ronintoadin", and "Mass Driver", "Cannon Soldier", or a card with the effect that states you can tribute monster to inflict damage directly to your opponents life points. "Catapult Turtle" will not work because "Ronintoadin"'s attack is far too low.
