Two things bothered me about slapping the title 'Bootleg' on them though - the first being that they had all the correct official copyright info, with the addition of 'Licensed by TOP-IN', and the second being that the cards so proudly declared FUNSKOOL all over the card, even though the original Base Sets had nothing to do with Funskool at all
More expensive rocks are slowly fading away as the game speeds up but in the average game stuff like this is still perfectly fine, not every card can be Sol Ring
There is effectively an in-built system for countering any destabilising effects from whales: the rarest cards are just even fancier-looking versions of the functionally identical, already-rare ones most non-spending people build their battling decks around
The other type are much better since you can search and find whatever card youd like
This wouldn't be the first Magic: The Gathering or MTG game on mobile and hardly the first video game adaptation of the franchise
The real decision that impacts your play experience will be how many other slots you replace with mana rituals, cantrips and tutors but Ill leave that choice up to you
