Enduring Vitality lets every creature you control tap for a mana of any color, turning a wide creature board into flexible acceleration. Vigilance helps its own body attack while remaining available to tap afterward. Creature tokens can contribute too, provided they are able to use tap abilities and have not just entered without haste.
If Vitality dies while it is a creature, its ability can return it as a noncreature enchantment that retains the mana-granting effect. That makes ordinary creature destruction less final than it appears, although exile can avoid the death trigger. Avenger of Zendikar’s Plants illustrate the potential mana supply, but freshly created Plants still need haste or a later turn before tapping.
Plan the turn around both the amount of mana available and the colors each spell requires. A hand containing Sol Ring can have plenty of total mana while still struggling with colored symbols. Keep reliable lands alongside specialized sources, and sequence the source that establishes a missing color before committing resources to a payoff that depends on it.
The returning enchantment can continue granting mana abilities even after its creature body is gone. If it later leaves as a noncreature enchantment, its own death-return condition does not repeat. This supports rebuilding around surviving creatures, but it does not make a board full of newly created tokens immediately usable for mana.
