Main combo:
Activate terraforming to get mausoleum, summon sage to get maiden, summon maiden using mausoleum, mausoleum effect targetting maiden to send bewd from deck to grave, maiden effect to special a bewd from deck, synchro using bewd and maiden to make spirit dragon, spirit dragon effect to special stardust spark, synchro using stardust spark and sage into cloudcastle, cloudcastle effect to revive spirit, xyz into true king.
Or, summon sage, sage gets protector, summon protector and maiden in hand, summon a level 8 however you want, synchro blue eyes and any tuner to make spirit dragon, spirit dragon effect to summon michael (use his effect if you want), tune michael and your other two tuners to summon cryston.
( This deck works best in MR3 format but I put this deck as link format because you can use it in link format decently, if you want to add links go ahead. :] )
