I can see it comming:
Me: " No i want to save my money and buy no steemmonster cards!"
SM:" Buy me buy me"
ME:" No "
SM" Come on you need this and this and this card in your deck to win more matches."
Me: " I stay strong, no new cards"
SM: "You need me! Buy now!"
ME: "Price is good... but only one card...."
PayPal: "Bill: 100 $ for 50 new cards"
