All-Seeing Arbiter - Borderless (SNC)

All-Seeing Arbiter
Casting Cost: {4}{U}{U}
Card Type: Creature - Avatar
Power/Toughness: 5/4
Card Text:

• Flying
• Whenever All-Seeing Arbiter enters the battlefield or attacks, draw two cards, then discard a card.
• Whenever you discard a card, target creature an opponent controls gets -X/-0 until your next turn, where X is the number of different mana values among cards in your graveyard.
  Artist: Anato Finnstark

Strengths:

• Card Advantage: The ability to draw two cards on ETB (Enter the Battlefield) and attack provides a constant source of card advantage.
• Debuff Opponents: The discard trigger weakens an opposing creature, which can be significant depending on your graveyard's diversity.
• Evasive: With flying, it's more likely to get through for attacks, triggering its ability more often.
• Decent Stats: 5/4 for 6 mana with flying is somewhat reasonable, especially considering the other abilities.

Weaknesses:

• Costly: At 6 mana, it's a bit of a late-game card.
• Discarding: Although it's tied to a beneficial effect, discarding can be a downside if you can't capitalize on it.
• No Immediate Board Impact: Apart from its card draw, it doesn't affect the board state dramatically when it enters the battlefield.

Deck Considerations:

• Discard Synergy: This card would work well in a deck that can capitalize on discard effects.
• Diverse Mana Costs: Because one of its abilities scales with the diversity of mana values in your graveyard, it benefits from a deck with a range of card costs.
• Control or Midrange: Likely better in a control or midrange deck that can survive to the late game to cast it.

Flavor and Art:

• Art: Anato Finnstark’s depiction adds an element of cosmic or mystical power, fitting for an Avatar creature.
• Lore: Likely a celestial or mystical entity given the Avatar typing and the "all-seeing" moniker.

Overall Impression:

All-Seeing Arbiter is a fascinating card with multiple avenues for synergy. Its abilities promote both card advantage and interaction with the opponent, making it a multi-faceted threat. While it may not fit into every deck due to its mana cost and specific synergies, it could be a powerhouse in the right build.
