Loyalty Manipulation

Cards that directly grow or duplicate loyalty counters on planeswalkers. Includes counter-doublers like Doubling Season, Vorinclex, Monstrous Raider, and Deepglow Skate; entry boosters like Oath of Gideon; loyalty-pumping spells like The Elderspell; and proliferate enablers like Flux Channeler and Pir, Imaginative Rascal that drop extra loyalty onto walkers already in play. Carth the Lion fits by making activated loyalty abilities net more counters. Co-fires heavily with superfriends.planeswalker_synergy, the broader view of any walker-helping permanent; this is the narrower view focused specifically on the loyalty resource. Distinct from superfriends.planeswalker_prevention, which keeps walkers alive against damage and targeted answers rather than feeding their counters.
