This deck uses the thunder dragons as engine for summoning titan + a link 4 pretty easely. It also uses the chaos engine as extenders for getting the combo easier. Also, it has thunder king rai-oh, so you can use it to disrupt and floodgate your opponent. Normal solar to send rai-oh to gy, get a roar or dark into the gy/banish zone (you can do it by using instant/retort fusion or activating allure), special dark by using hawk or banish roar by using a chaos monster to summon dark from deck, summon solar token, link dark and the token into some summer summoner and add fusion, use fusion to summon titan, then if you have another extender, use it and link it with solar into masquerena, during your opponent turn discard a card to summon rai-of from gy (some summer summoner effect), then activate masquerenas effect to link it and sss into a 2 negates apollousa. I know you wouldnt be summoning rai-oh to often on your first turn, but you can easely abuse this combo on your next turns as it is searchable by the fusion.
