Ajani, Sleeper Agent

The compleated cycle turned a familiar phrase (Phyrexian mana) into narrative machinery: a set of planeswalkers whose corruption is baked into the mana symbol you tap for. Here the fiction and the math line up cleanly. Pay the with two life instead of a mana, and the walker arrives with two fewer loyalty counters, entering at 2 instead of 4. That is the whole trade the card offers up front: a mana-efficient tempo start against a fragile board presence, and the choice sits with the caster rather than being dictated by the deck. The loyalty penalty for cheating the cost is a rare instance of Phyrexian mana carrying an actual downside beyond the life payment, which is what makes the design more than a discount.

Underneath the corruption theme is a genuinely coherent green-white toolbox. The plus filters toward creatures and planeswalkers, feeding the same board it protects; the minus three spreads three counters and vigilance, a defensive-into-offensive pivot that keeps the walker alive while it grows a threat. The ultimate is the tell that this Ajani is no longer entirely himself: an emblem that hands out poison counters off your own creature and planeswalker casts, folding an infect-adjacent alternate win into what reads on its face like a straightforward permanents deck. It is the poison payoff dressed as a counters-matters planeswalker, and the emblem is where the sleeper wakes up.
