Citanul HierophantsHow it works & interactions with other cards

What It Does

Citanul Hierophants grants a static ability that provides a new activated ability to every creature you control. Specifically, each creature gains '{T}: Add {G}.' This does not replace any existing abilities the creatures have; it simply adds an additional utility option. This effect applies to Citanul Hierophants itself as well, meaning it can immediately tap for mana if it doesn't have summoning sickness.

How It Resolves Step by Step

First, Citanul Hierophants enters the battlefield and its static ability immediately applies to all creatures you currently control. If you play a new creature while the Hierophants are on the field, that new creature also gains the ability. To use the mana, you simply tap an untapped creature you control during a window where you have priority or while paying for a spell. Note that the creature must have been under your control since the beginning of your most recent turn to use this ability, unless it has haste.

Common Mistakes

The most frequent error involves summoning sickness. Even though Citanul Hierophants gives creatures a mana ability, they are still subject to the rule that prevents creatures from tapping the turn they enter the battlefield. Another common mistake is forgetting that the ability is lost if Citanul Hierophants leaves the battlefield. If an opponent destroys the Hierophants, your other creatures immediately lose the ability to tap for green mana.

When to Play It

This card is best utilized in 'Go-Wide' strategies where you have a high volume of low-cost creatures or tokens. It is particularly effective after a board stall where you cannot safely attack, allowing you to pivot those creatures into mana to cast a game-ending threat. It acts as a force multiplier for every creature spell you cast thereafter.

Interaction examples

Recovering Resources

Eternal Witness

With Citanul Hierophants on the board, you cast Eternal Witness to return a card from your graveyard to your hand. On your next turn, that Eternal Witness can now tap to produce {G}, essentially paying for a third of its own mana cost every turn it remains on the battlefield.

Value Ramping

Solemn Simulacrum

You play Solemn Simulacrum to search for a land, increasing your mana base. If Citanul Hierophants is also in play, the Solemn Simulacrum provides double the utility: it fetches a land and can also be tapped directly for {G} starting the turn after it was played, accelerating you toward your high-cost spells even faster.

Self-Activation

Because Citanul Hierophants says 'Creatures you control,' and it is a creature itself, it grants the ability to itself. If you can give it Haste or if it survives until your next upkeep, it can tap to produce {G} just like any other creature it is currently buffing.
