As you can see in the extra deck, i chose to not just use standart extradeck cards like Nibiru, Ash-Blossom, etc. Instead i used the extradeck to give u some variations of the Deck. I built all three options for the TCG, but if u play Online or TCG/OCG, there is a fourth option which includes the Predaplant-Dragun-Engine. Just include DM, RE and R.E.F in the Main-, and Predaplant and Dragun in the Extradeck. (Kick out 3 of the equipspells)
The other two options obviously are Exodia FTK, and Apex Avian Lockdown. Exodia is of course the most inconsistent but still works very well. Apex avian is pretty consistent but i like Zexal best for beeing the most consistent.
Strategy is simple: Summon two samurai, isolde, battle shogun, gateway, skulldeat, generate plus, build a board of naturias, cristalwing, apollousa and zexal.
