Each prize consisted of a different Pikachu card, where each illustration depicts Pikachu holding a different trophy
That is something I would personally avoid
Drawing cards when creatures with flash or haste die is decent, especially if you're making hasty tokens that sacrifice at the end of turn with something like Reflection of Kiki-Jiki, but it pales in comparison to the last ability
If, however, your child wants to actually play the TCG, theres a couple of excellent starting points we can highly recommend, depending on your childs age and/or experience with card games in general
The ability to grow and also draw cards whenever a creature enters keeps the green deck going
It is an impressive design feat getting so much power into a card that is neither broken nor unplayable
