Sun

The Sun is the planet of the self, will, energy and power. It is the most important planet in a horoscope, and a heavily afflicted Sun in a natal chart makes it difficult for the subject to get anywhere in life, as they will not have the basic self-belief and stamina required to progress.
power: gift of light and life
bestow upon anything the gift of light and life. Once captured, all nine planets will be granted this, if handed to the right leader.

Mercury

Mercury is the planet of the mind, intellect and communication. In a natal chart, the aspects and position of Mercury show the ways in which subjects use their minds and how they get their message across to others.
Power: Mind Reader
before the equine attacks, the mage who contains mercury's power will beable to know what that horse is doing, preventing one full attack (it can be a power attack also)

Venus

Venus is the planet of love, higher emotions and artistic sensibility. The aspects and positions of Venus in a natal chart indicate how the subject deals with relationships, sexuality and social interaction, as well as their capacity for creating and appreciating beauty.
Power: infactuation spell
those who possess this will be able to "freeze" their opponent during one of their attacks, while they stand and admire you're planet-given beauty.

Mars

Mars is the planet of action and the expression of will through activity. A heavily afflicted Mars in a natal chart may give the subject impulsive or violent tendencies. Favorable influences may channel the energy of Mars more positively, into strength, determination and achievement, for example.
Power Jackel
growing elongated, sharp teeth and nails for one attack, you get the point.

Jupiter

Jupiter is the planet of expansion, growth and cooperation. In a natal chart, the aspects and position of Jupiter indicate how subjects are able to expand their horizons, and how they fit into and contribute to society.
Power:distant horizons
Bring whatever storm you wish, hail, fog, highwinds, directed right at you're opponent. Use your imagination

Saturn

Saturn is the planet of structure, limitation, experience and discipline. A heavily afflicted Saturn in a natal chart can leave subjects selfish, rigid and limited in their ability to interact meaningfully with others. Favorable influences can make them ambitious, successful and self-disciplined.
Power: Senseless
blind and deafen your opponent for one attack.

Uranus

Uranus is the planet of innovation, nonconformity, higher intuition and inspiration. In a natal chart, a well-aspected Uranus can bring a touch of genius to the subject, while a heavily afflicted one can lead to eccentricity and unreliability.
power: invisibility
become invisible for one attack

Neptune

Neptune is the planet of transcendence, higher faculties and psychic abilities. In a natal chart, the aspects and position of Neptune deal with the subject's ability to access higher consciousness and their grip on reality. A heavily afflicted Neptune can lead to unrealistic expectations and self-deception.
Power: freezing time
you may freeze time for one complete attack, this can work as a defense also

Pluto

Pluto is the planet of deep, impersonal energies and transforming forces. In a natal chart, the aspects and position of Pluto indicate areas of life in which the subject is capable of making fundamental changes, for better or for worse.
power: transform
you may transform into any animal you want for one attack/defense
