In the first trade, they’re just short. Your store pets are worth an ‘09 rare each, and they’ve only got 3 ‘09 rares worth. They would need to add.
In the second trade, it’s very unfair to you. In C$, your store lions are worth between 35-40 C$, and probably the higher end. They could easily go for 1-2 ‘09 rares each due to demand. They would need to add.
