I'm not the most familiar with the gladiator beast cards, but let's give these a look
( quick thing of note, your card arts are pretty sweet )
Cestus: It's effect is pretty good. It allows you to special summon any main deck monster to your field, giving more utility to to your monsters and making the higher level ones easier to summon ( Augustus mainly ). Effectively, it's a lonefire blossom for the archetype, and a much better form of test tiger. Shuffling as a cost is interesting, given that if your opponent negates it you still have to shuffle it into the deck. A hard once per turn works very good to prevent you from using it too much. A good card all around.
Field Spell: Gladiator Beasts do already have their own field spell, but it's absolutely awful so any replacement is welcome. Attack boosting is always welcome since this is a battle-focused archetype. The attack changing effect is interesting, as you showed in your replays, as you can summon Nerokius and prevent your opponent from effectively attacking you ( given his armades effect ). The searching is pretty good. It allows you to play war chariot over solemn strike ( since it's now searchable ) and gives more utility to the other gladiator beasts spells and traps, since they are searchable. Another good card.
Fusion Spell: Essentially this is a miracle fusion for the archetype. It's a surprise that the archetype doesn't already have something like this, given that Neos got one. It works pretty well for this archetype. It gives your monsters great recoverability, allowing you to go into a late game Gyzarus and destroy 2 cards with his effect. As you showed in your replays you can go into Tamer Editor easier, and that card has some great utility. The protection effect is like that of Return of the Dragon Lords, which is pretty nice, given that if you summon Gyzarus off of this effect you turn him into a Dragon Spirit of White ( getting rid of back row and protecting himself even if your opponent has a solemn strike ). A great card for this archetype.
Gladiator's Revolt: A trojan retrain effectively. Always nice, since that card ( much like the original field spell ) is completely awful. It takes a monster from your deck instead of from your hand, allowing you to not go into a minus just to draw 1 card. It also sets up your plays if you run Taming, as showed in your replays, effectively a two card combo into any monster from your deck. You can tell how much synergy these cards are supposed to have with the older gladiator beast playstyle, and I can definitely appreciate that. A great card all around.
As for the replays, that's a spectacular addition to your post. We all could speculate on what a card COULD do but you went ahead and showed us all just how they work in actual games. Well done, it's above and beyond anything I expected from a set of custom cards. It's pretty neat to see the cards in action, and it even taught me some things about cards I didn't know existed before reading.
Overall, you did a pretty good job :D
