I'm starting MTG today, first time ever I'll play the game. I was looking at the rules online but one thing I couldn't find a good answer. Some guys I see playing do one way and others do other way.
So I don't know if this is something that each one defines or if there is an specific rule about it.
For example, if I have a card that requires 3 mana to be used, does that also apply to put the card on the table? Example, I need to have the 3 lands required in order to drop the card from my hand to the table?
Or can I put the card on the table at any time but only use it when I have the 3 mana required? Only thing I could found about it is to actually activate the card, but not using it on the table.
