Toly
The ArchitectYour casino is a latency problem.
The humble-genius who ships first and says something deadpan later. His whole thing is time itself: the timestamped clock that always increments, precise and unavoidable. He reads like just another coder, not the mind under the Chain.
His deck is a control and tempo engine that leans on Spells and Spell Power. Soften a board, ping the exact thing that needs pinging, then close with a burst. He is unsentimental enough to name his signature Spell Proof of History while his Protocol is Timestamp, and to replace his own invention while the clock keeps running anyway.
