its really complicated to explain how the combo goes but basically you want to ladder through all of your links and then end on the clock dragon into clock lizard then resummon the clock dragon.
Tips:
-You cannot use Transcode Talkers effect because it locks you into Cyberse monsters for the rest of the turn which means you cannot summon the Levianeer or the catapult turtle.
-The Link Ratings that you banish off of the 2nd effect of Clock Dragon must equal EXACTLY the amount of cards that you have left in deck. If the link ratings are too high you cannot activate the Cyberse Clock Dragon's effect.
-You must search the Clock Wyvern off of Codec when you summon Excode Talker
-You can use Firewall Dragon to return extenders to your hand. Most of the time you want to bounce the Clock Wyvern after using it to extend.
-There is too much to explain so im gonna give up here
