the trick here is to go to ygo top decks on YouTube he explains the combos and even enhances the deck. if there were 5 levels this would be level one but still I will show you this 1 card combo that comes in handy
step 1 have fire formation tenki in you hand and activate it
bring ratpier to hand and then summon it
send ramram to grave
using ratpier xyz into chakanine
activate chakanines effect and de tach ratpier and sp summon ramram to field in defense
just xyz summon until you see an opening for fist of the brotherhood eagle and then link summon him
activate his effect
using eagles nasty ability you can now bring tenki back to hand and send brotherhood buffalo to grave
activate buffalos effect to summon its self from the graveyard and then if you have eagle buffalo and any different card link into any link 4
