Fate/Domination Servant Overviews

Saber
Common Class Card - Negate Magic

Altera - Destroy civilization for high mana discounts and huge colorful power.

Artoria - Negate Strength (and/or Magic, as usual), and unleash Excaliblast to hit hard on climax.

Arthur - Negate Strength (and/or Magic, as usual), until you sacrifice them to make your Excaliblast hit harder.

Barghest - Punish opponent's activated abilities, and gain high power from a triple-3 hand, which you can also preserve at the risk of relying on card draw luck to dictate when you can unleash it.

Bedivere - Sacrifice remaining deck for cheap powerful bursts, while gradually becoming weaker with each deck cycle.

Charlemagne - Cycle color-boosting Objectives while enhancing their effects on your skills.

d'Eon - Parry opponent's attacks with your own equally-powered cards.

Dioscuri - Double attack modifiers while dealing with attack restrictions that your skills can help work around.

Gawain - Gamble on high-risk-high-reward committments for higher power, particularly through 3-power attacks.

Iason - Send Argonauts on Quests so they get added to your attack when drawn from Objectives.

Jacques - Forcibly generate Foreigners for other players while reducing their benefits for them.

Lakshmibai - Play attacks when people move to you, including the option to kick them out.

Musashi - Gain mastery from winning fights to power up your attacks.

Mordred - Spend mana for proportionally (and potentially huge) power of your choice, with the flexibility of deferring the decision to Combat phase alongside other attack options.

Muramasa - Burn basic attacks for power, and get one final chance to unleash all the burned attacks at once.

Nero - ???

Okita - Draw cards to hit harder, with the risk of randomly breaking down from your weak constitution with each draw.

Saitou - Conditionally negate Agility and/or Strength cards, with the option to sacrifice the reliability of negation to potentially play more attacks for power.

Siegfired - Lose successively more VP to protect yourself from effects and also from a weakness that would otherwise have been exposed from your cheaper (but still powerful) NP.

Sigurd - Reveal NP to burn basic attacks to double their power (and maybe another NP to absorb mana), with each revealed NP extending color diversity but also continuously draining VP.
