So, in a short phrase, spright elf + halq + formula synchron and a Lvl 8, enable you to make, 2 synchro 10 monsters on your opponents turn, the first one being the sincro 10 zombie made with doomking or any lvl 8 on field and formula synchron summoned from Halq. On res, elf, target formula, zombie sincro 10 targets lvl 8 from grave (keep in mind zombie world is up, if not, your only target might only be doomking then). Re-summon, make a baronne or chengying, because probably going first you already end on baronne, + elf + vampire zombie or halq and it will still enable the combo either way. How you say?
Punk + Extender (ANY),
you go on with your usual punk play to ruler, ruler revive a 8 if you need to, go xyz vampire, mill, at this point you should be golden if you dupped a changshi (because this will be the dark target for banishing to revive ruler), link 2, and later make elf out of that link 2, or if plague spreader or the clown lvl 2 happen to appear milled, well make it wih them. Elf revives a lvl 2 if you have, if not, at this point.
We revive ruler, banish changshi and foxy tune. Revive changshi banish any zombie milled, or if you already revived uni zombie than you probaby have world up to banish anything if no field spell is up, banish vampire xyz, as this makes the combo useful even without zombie world.
Changshi send to grave a mezuki/gozuki whatever you can get to continue and extend. for basic sakes, lets say since no zombie world and only chengshi mill, we send plague, revive plague with elf, make halq, get glow up bulb or tuner needed, plague effect, make barrone, plague and chaotic banished, you can now make i:p with the glow up bulb, and halq, and on opponents turn you revive the halq, go for avramax + draw from formula, and whatever in hand left (probably 3). This would be the worst outcome.
If you milled a way to put zombie world, summon punk combo and now starting uni zombie after resolving vampire xyz: You can send another mezuki or a chengshi, lets say chengshi, make halq uni + xyz, glow up bulb + halq, ruler, banish chengshi and foxy tune, revive, chengshi banish any zombie, revive, send zombie clown, revive clown by its own effect, target lvl 6, revive, make zombie sincro lv6, send mezuki, makes the lvl 6 a 2. make barronne ruler + sincro 2 since its a tuner.
field, Baronne, halq and bulb, mezuki revive gozuki = (if zombie reborn in grave, trigger its effect, recicle mezuki), now gozuki send mezuki, and mezuki can now revive another monster, such as a lvl 4, or a lvl 8 punk milled) or you can make elf, mezuki revive halq point down elf.
Field is now, baronne, elf, glow up bulb, halq, gozuki, you can go link to with gozuki and glow up, makle vampier zombie under elf, summon doomking, elf effect revive clown, make sincro zombie 10 and on opponents turn if baronne negated before, recicle it, and on your opponents turn make baronnen and chengying with loop.
the rest of theses combo all start the same point, after zombie xyz its off to the raises to revive loop and get to that board, i will think of a way to fit in appoulusa
