Celestial Regulator
Casting Cost: {1}{W}{U}
Card Type: Creature - Angel Advisor
Power/Toughness: 2/3
Card Text:

• Flying
• When Celestial Regulator enters the battlefield, choose target creature you don't control and tap it. If you control a creature with a counter on it, the chosen creature doesn't untap during its controller's next untap step.
  Artist: Mathias Kollros

Strengths:

• Board Control: The card's ability to tap and potentially "freeze" an opponent's creature can swing the game tempo in your favor.
• Evasive Ability: Flying makes this creature difficult for many decks to block.
• Synergy: Works well in decks that utilize counters, making it more likely to lock down a target.

Weaknesses:

• Mana Requirements: The card is two-colored, requiring both white and blue mana.
• Limited Impact: Its tap effect is powerful but might not be game-changing, especially if you don't have a creature with a counter on it.

Potential Deck Placement:

• Likely to see play in Azorius (White-Blue) Control or Midrange decks that make use of counters.
• Could also be useful in Bant (Green-White-Blue) decks with a counters subtheme.

Flavor and Art:

• The artwork and card name evoke a sense of celestial authority and guidance, which align well with its board control effect.

Overall Impression:

• Celestial Regulator is a solid card that provides some board control while also being a decent body in the air. Its tap and "freeze" ability make it a valuable asset in controlling the board, especially in decks that utilize counters.
