Hypothetically the player has an abundance of energy counters, they can easily pay energy counters equivalent to the mana cost of the copied creature during their end step to keep them on the battlefield permanently
You can counter and interact with the card the same way youd counter or interact with anything else
Then theres Kroxa, Titan of Death's Hunger, Fear of Missing Out, Dauthi Voidwalker, and other cheap powerhouses
In this case, Bridgeworks Battle is an easier-to-cast Savage Smash, which is situationally quite powerful
For this reason, I stick to major vendors when I deal in damaged and heavily played cards
Thanks to a series of very lucky coin flips in my favor, Kyurem couldnt attack, and I stayed alive long enough to draw a better Pokmon
