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

If I don’t play a Tamer using this card’s <On Play> effect, does that prevent my opponent from playing a Tamer card, as well?
No. Even if you choose not to play a Tamer, your opponent can still use this card’s effect to play a Tamer of their own.
