1 official ruling from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

If the cards I reveal from my deck for this card's <On Play> effect include both a [Kiyoshiro Higashimitarai] with [Jellymon] in its text and a non-[Kiyoshiro Higashimitarai] card with [Jellymon] in its text, can I choose to only add one of them to my hand, and place the remaining cards at the bottom of my deck?
No. If you have cards that are targets of this effect, you must add as many cards to your hand as possible. However, because one of the cards revealed and added to your hand is a [Kiyoshiro Higashimitarai] card with [Jellymon] in its text, that card fulfills ""card with [Jellymon] in its text,"" so you may just add that [Kiyoshiro Higashimitarai] card to your hand and return the non-[Kiyoshiro Higashimitarai] card to the bottom of your deck without adding it to your hand.
