Forum:Madolche Tea Break question

Madolche Tea Break Sorry if I did the Internal linking wrong, first time trying.

I know it will force your opponent to repay costs (life points, discard, etc.) if they wish to play it again, but do lingering effects still go through, or is it negated completely?

Example A) Opponent plays Pot of Duality, I chain Madolche Tea Break, and the spell returns to their hand. Can they play it again right away, or are they under the other effects of Pot of Duality?

Example B) Opponent play Allure of Darkness, I chain Madolche Tea Break, and the spell returns to their hand, do they still have to banish a dark from their hand?
