The Pokmon Trading Card Game has fared a lot better in this regard, as very few cards have ever been officially banned in tournaments
For example, if an enchantment creature with the bestow ability (an ability that allows a creature card to be cast as an Aura instead) is an Aura and the target of Kaya's last ability, the ability will not create a copy of it
If you need to counter a planeswalker or another non-creature spell, it's clearly better than Izzet Charm since it only costs one mana, but if your opponent is drawing cards with a Dark Confidant or has so much mana they can easily pay two extra for their spell, it's stuck rotting in your hand
Ramp decks are not about giving your opponent a load of mana too
Once Hashaton is on the field, he provides a transformative creature-copying ability that not only aligns the copy token with the zombie type but also makes it a 4/4 for just three mana
Thats the more instructive number of the two it isnt launch hype, its where the market put a Charizard MUR after nearly a year of supply
