Q1: When I place this card in my battle area, can I use a blue Option card even if I have no other blue Digimon or Tamers in play?
No. Having this card in your battle area doesn't fulfill color requirements.
Q2: When I place this card in my battle area, can I activate this card's Delay effect even if I have no other blue Digimon or Tamers in play?
Yes, if this card is in your battle area, you can activate Delay, regardless of color requirements. Color requirements only matter when using Option cards.
