A Giant Ballpark deck built on getting rank 4 monsters out. Also helps with link plays given you have so many monsters on main phase 2. One card that may do well on this deck is Apolloua, if you prefer that card over something like Berserker of the Tenyi or Bagooska. Accesscode is a bit difficult to make cause it requires effect monsters, so that can also be switched out for something else. If you like any rank 4s that require 3 xyz material, it's easy to get those out as well. Bagooska is mostly meant for stalling until your next turn when you can finish off your opponent. If you wanna play Gagaga Cowboy, that's an option, though it doesn't deal enough to finish them off, usually.
A few decent cards, if you don't like Doom Dozer or Aztekipede, are Beetrooper Sting Lancer and Tree Crown Armorperor Beagram. Sting Lancer might be a decent option for going second, which is the entirety of this deck, as well as anti-some-GY-effects. Beagram is good for protecting ballpark, or just a free special summon.
