Invoked deck, allows you to make Stardust Sifr using Necroid Synchro. Handtraps and kaijus for general matchups, usually blind second. Ideally use Raidjin to flip Sifr face-down, then flip summon it next turn to get its effects back. Terraforming for Megaroid and Meltdown. Megaroid searches Necroid (yes, really). Usually either use Gadarla with Debris Dragon or Thunder King with Ash Blossom/Ghost Ogre for Necroid Synchro's cost. If Instant Fusion gets unlimited, replace Keeper of Dragon Magic with more copies of it, as they exist to search it out. Gadarla over Gameciel because he's wind attribute and you can use Super Polymerization with Aleister to go into Raidjin, who you really want on the board.
