Springans is insanely great with the new inclusion of Champian Sargas and Tallyho. This deck allows you to go into a cool neat endboard using only Field + Springans name. The Crystal Beast engine gives the deck another way to perform combo by nsing pegasus, pegasus equip crystal beast rainbow dragon, and crystal beast rainbow dragon summoning another pegasus. The deck also uses Rainbow bridge, which adds a crystal beast and golgonda to your hand, so you're basically playing 3 terraformings along with springans watch and springans booty, it's crazy!
Your endboard can vary, field + name ends up in Champ Sargas, regular Sargas, and either an xyz or I:P for unicorn, either way the deck is pretty versatile when it comes to either going first or second. The endboard not be as strong as Tearlament and Kashtira, but it does work! Try it out!
