When General Leo Cristophe enters, return up to one target creature card with mana value 3 or less from your graveyard to the battlefield. Then put a +1/+1 counter on General Leo Cristophe for each creature you control.
Flood the board with cheap, value-driven creatures, then deploy General Leo Cristophe to reanimate a key threat and balloon himself into a huge attacker. You grind incrementally with white's go-wide tools and small reanimation, swinging with a wide team backed by anthem effects and recursion to close games.
Mono-white consistency and access to powerful tax/stax and recursion pieces
Built-in mono-white reanimation for 3-MV-or-less creatures on every cast
Scales well in token/go-wide shells since Leo grows with your board
Cheap to recast relative to payoff if board is wide
Mono-white card advantage is historically poor without dedicated engines
Leo dies easily once he's a big single target; spot removal is brutal
Reanimation capped at MV 3 or less limits the ceiling of recursion
No evasion baked in, so a fat Leo can be chump-blocked
Solves mono-white's mana and card limitations, fueling a faster, bigger board.
Add fast mana and white staples like Smothering Tithe, Esper Sentinel, and Mana Crypt to fix mono-white's card and mana shortfalls. Build blink/recursion loops (Conjurer's Closet, flicker effects, Sun Titan) to abuse Leo's reanimation, and add protection like Swiftfoot Boots and Teferi's Protection to keep the board intact. Tighten the curve toward efficient ETB creatures so every Leo cast brings back something impactful.
