Titans' Nest is a great card, however doesn't work as dynamically as it should. In this scenario, i had tapped my Golden Goose for the incorrect mana before I removed the cards with Titans' Nest, when I attempt to undo the issue with Golden Goose, I cannot undo further back than Titans' Nest's removal of my cards. causing me to loose the game. 1 turn before this, I had attempted to cast my Ethereal Absolution with Titans' Nest's activations already happening, I attempt to cast it, but it turned out that I didn't have the appropriate mana, so the game just returned the card to my hand , but kept my mana tapped and was screwed for that turn before also. Titans' Nest needs to be fixed to be more intuitive and less buggy to use. If i make mistakes with it, very easy to do, cannot be undone.

Instead, mana needs to be added before cards are removed, then once the card is cast, then cards should be selected to be removed. The system doesn't even know how to take Titan' Nest's actions back.

Thank you.
