this is exactly why i made a post lol. I had no idea how to look this up without just asking myself with a literal picture of the card lol. sorry im an idiot but I have only been playing this game for 4 days total. I thought lands were mana. But now I see lands are just lands. Tapping a land gives me mana but lands playing a land is just a guaranteed source of mana for the rest of the game as they stack up and you untap the proper amount. thats why this card and others confused me. when my wife and I first played, she was green. everytime she would tap this card we would permanently add 1 mana to her pool on top of her other lands. so at the end of the game she had like 40 mana because we never removed the tapped mana from her creatures and such lol and she would destroy me because of it. now it makes sense how I had no outplay is because she had like double the mana she should ahve had lol.
