What about this?

Banish 1 "Cyber Research" Ritual Monster and 1 "Cyber Research Gashat" Ritual Spell from your GY; Special Summon 1 Dragon monster with 2500 or more ATK and 2000 DEF from your Extra Deck, Deck, Order Deck, Gravity Deck or Paradox Deck. (This is treated as that monster's corresponding Summon.) You can only activate 1 "Rainbow-Eyes Gashat" per turn.

Ah, and the Cyber Research archetype has 39 cards, so this one suffices.
