It was after my second game with Yarok, where I assembled infinite mana in barely any time with Deadeye Navigator/Peregrine Drake and cast Villainous Wealth for X = 1,000,000, that my friend observed: Wow, its almost like getting two triggers for every enters-the-battlefield effect is broken. And they were right
I think the biggest thing here is that there was just a missed opportunity for PSA to pair this with a change that would have benefit both users and the company at the same time, buying some goodwill
A lot of hydras are very efficient at their mana value and a lot of them have X in their cost which scales with the game or allows you to spend more mana on their activated abilities
Ive never played Sword & Shield and never plan to, but I cant imagine the games are able to do anything remotely as interesting with the Galar region as this
You can play a land only during your main phase when you have priority and the stack is empty
