Prima Light is a terrible card. Not sure why you'd want it. Even if it was literally just "Tribute 1 monster; Special Summon 1 "Cyber Prima" from your hand, Deck, or Graveyard.", it would be mediocre at best.
But two of those cards are garbage and the other's stupidly powerful here... Why should ANY of them be a thing?
Alexis could get more stuff. Most of the new Cyber Angel cards are probably within DL's power level. But none of remaining the cards she's actually used in the anime are happening, mostly because they suck or are Doble Passe, Natasha or Vrash.
