From trading cards to PokPark KANTO, theres so much you dont want to miss out on
The issue is that they are very well done and manufactured in a larger scale than previous fakes
When you have access to the best mana ramp, tutors, and card draw effects in the game, it wont take long to build huge hydras like Hydroid Krasis, token generators like Empty the Pits, or powerful payoffs like Villainous Wealth, all of which can be doubled on the cheap via Unbound Flourishing and will be making huge attackers simply for casting these spells
Tymaret, the Murder King will do extra murdering, and so on
The others have no effect
The halls of Mist, also had a Cumulative Upkeep, although more reasonable at just one colorless Mana and would prevent creatures from attacking two turns in a row
