Towering GibbonHow it works & interactions with other cards

Scaling Power and Reach

Towering Gibbon features two distinct abilities. First, Reach allows it to block creatures with flying, even though it does not have flying itself. Second, it has a characteristic-defining ability that constantly checks the mana values of other creatures you control. Its power will change instantly if a new creature with a higher mana value enters the battlefield or if your most expensive creature leaves.

How it Resolves

The power of Towering Gibbon is checked in all zones, not just while it is on the battlefield. Because its power is defined by a star (*) in the power/toughness box, its value is calculated even while the card is in your hand, library, or graveyard. If you control no other creatures, its power will be 0, but it will always check its own mana value if it is the only creature you control, resulting in a power of 4.

Timing and Strategy

You should look to play Towering Gibbon when you already have established a board presence with high-cost creatures. Because it lacks Trample, it is often best used as a defensive anchor against flyers or as a high-power attacker when the opponent's board is clear. Remember that mana value is determined by the symbols in the top right corner of a card, not by how much mana you actually spent to cast it.

Interaction examples

Standard Midrange Setup

Eternal Witness

If you control Towering Gibbon and Eternal Witness, the game checks for the greatest mana value among your creatures. Eternal Witness has a mana value of 3, while Towering Gibbon has a mana value of 4. Since 4 is the greatest mana value, Towering Gibbon becomes a 4/4 creature.

Increasing Strength

Solemn Simulacrum

If you already control Towering Gibbon and then cast Solemn Simulacrum, both creatures have a mana value of 4. The greatest mana value you control remains 4, so Towering Gibbon stays a 4/4. However, if you were to play a creature with a mana value of 5 or higher, Towering Gibbon's power would immediately increase to match that new value.
