In truth, what Harvard did was simple, too simple in fact. A shimmer was visible around his chest, a scatter of shards that set as bait. All it needed was a small light source in order to refract the shards, allowing its magic to be casted. Those shards were, in fact, of a gem. A jewel. A Spell. One that allowed him to implant his illusions onto it and set it up as if he was casting them himself. A stricter trap, but with a stronger payout in comparison to other spells that could function the same way, as the energy takes both the environment and the light into its factor.
The Devil's Eye.
While originally it was supposed to be used as a substitute catalyst for stronger illusions, namely ones that utilize the sun, Harvard allowed Illusion to act as a simpler, yet stronger output. Furthermore, by keeping his energy contained within the gem during the card's transfer, it allowed him to keep such a spell intact even after it was scattered all over the undershirt. Criollo can't help but be impressed at how he prepared for what was going to happen, pondering at what point he took such a trick. The Group, despite being far away, were able to see those small glimmers, letting Envy understand when. "You kids really were prepared for the War, huh?" He'd mumble, keeping his voice low so the other Guards don't overhear the current events unfolding. Zazel would be quick to nod, a prime witness to Harvard's trickery, one that stumped him on multiple occasions.
"It's a habit for him at this point to prepare and pull the rug on people when they least expect it." Zazel explained, a small sentence that emphasized Harvard's playstyle: To deceive and take what he wants when its wide open. Once the Card Magician sees the struggle against such webs falter, he'd take a long breath and sit himself down, patting the Automaton on the head. A clear, simple victory.
Yet... Even he knows that he wasn't done yet.
When he tried to touch the Automaton, he would feel the effects of Criollo's magic once more. His sense of touch seemed to have disappear, as if he can't feel the cold metal. Furthermore, his other senses began to go away as well, encroaching into his taste, his smell, his hearing, and finally his sight. He tried to move his body, yet even then, he didn't felt his muscles following. He doesn't know exactly if what he was doing was even successful or not. It felt like it was taking ages, trying to wait out what felt like some sort of curse, before finally being able to regain his touch, a tap against the boy's shoulders. He was tagged. He'd try to set up a spell, a chain to tether himself into the Automaton, letting it trigger and snare the boy, letting his soul depart through the web, temporarily leaving his body for dead, as he'd use its mirror-like face to inspect what happened. The cocoon he made around Criollo was gone, slashed horizontally, as well as visible footprints to track the man behind Harvard. The air wafted with a chocolate-like scent, the beams mostly leaving behind such a trail with each impact, filtered out once Criollo has made use of them through the crack, now expanding to be a sizable hole. It must've amplified its effects when such mass coated the area, a similar feeling he felt when dealing with Jesta Spade during his own trick.
He could feel his body growing a bit cold now. His time was already spent investigating the setting. The body was still functional, letting Harvard cast one more spell before needing to transfer back, switching up Uru and waiting standby for another Monster to be inserted, whilst traveling Uru to another source. Harvard would choose to revert the spider monster as pure energy so that he can both boost himself and spend less when selecting the next beast, finally given back his proper body, and thusly, his senses again. "You were hiding there, weren't you? In that Machine?" Criollo asked, as the Chocolate aura was already making the two seals defunct, as well as repairing and planting back the candies and frosting from his cleaned axe, allowing him to dual wield once more.
Harvard chooses not to answer, letting the Automaton fire a blast down at the Guard, its newest monster quick to adapt into the Aura: Adam. Such a blast was quick on drawing in the Chocolate, enhancing its properties as it tries to nullify and take away Criollo's senses, forcing him to parry with his Axes, letting the candies take the full blow. Right as he did, Harvard would trail up one of his cards into his mouth and cast down Chains, snaring the Guard by his wrists, pulling him closer and letting the crumbs scatter so that it can serve as a trap for a later use. Harvard lets one of his cookie arms take a clean jab straight into the Guard's ankle, before casting a spell and cutting the distance, moving him outside of the barrier. "Tag!" He'd shout, watching from the other side as he'd be careful not to get into the aura again. Despite such set-up and intensity, Harvard and Criollo were actually enjoying themselves, trying to figure out one another with their current arsenal. The Guard was quick on launching a slash against the barrier, shattering it once more.
Harvard was adamant this time on seeing what his other sleeve contained.
He'd set the chains down once more, letting it trail from the ground to touch the crumbs he left behind, taking a card and casting it through the metal, the energy visible to its trail like a spark across a stick of dynamite. Criollo jumped up, expecting for the boy to cast some bombs or a virus again like before, yet was instead met with a new figure, a Lesser Monster in the form of ghosts and phantoms.
Despite being smaller than a kernel's worth of gold, the Phantoms were exceedingly fast, as they touched into Criollo's feet, ready to strike into his soul.
