Two main plays are to spam out a rank 10, and use top of deck calls for card advantage.
The Level 10 materials for XYZ are: Obelisk from a True Name, Exodius via its own condition, Metal Reflect Slime with a possible stop at Egyptian god slime now that that's a thing, and Accel (sending Quickdraw to up its level) made out of Deep Sea Diva and Gishki Diviner. From there you have a simple choice of Number **, Gustav into Liebe, Galaxy Destroyer. Accel and Quickdraw can also make a Cyber Dragon Infinity.
Plays with Reckless Summon are for Diva into triple Diviner for draw 3 and Trish Zero, or for triple quickdraw into CDI and maybe a Chevalier De Fleur for the extra negate.
The card calling is mostly True Name for the quick Obelisk, or Sphere Mode if your opponent has troublesome cards that need to be cleared. Diviner and Archfiend's Oath can generate extra cards in hand, especially with Oath being a soft once per turn. Convulsion, Card Advance, Spellbook Organization, and Diviner can be used for either a peek at the card before it's called or even a top of deck fix before calling.
