Ra's Disciple is a LIGHT fairy with 1100ATK and 600DEF. The very last line of it's effect states "You cannot Special Summon monsters, except by the effect of 'Ra's Disciple'.". A quick trip to the wiki confirms that this is a continuous effect, and so is active all the time that Ra's Disciple is. He has three of them out on the field when he Synchs for Royal Guard. 

Cause otherwise you'd see that card everywhere in R4nk or Frog Driver Decks, given that drawing into one means having the three of them out immediately.

Ahhh, OK. Wow, can't believe I missed that. Yeah, [@KOgaming], that's an illegal move you made. You should probably fix that somehow.
