Hello everyone..
Can anybody tell what are some good two-player card games? Your ideas highly appreciated here.Thanks in advance.

Superfight Game

Grocery store game: The first player says "I went to the grocery store and bought..." and chooses something that starts with A. Player 2 repeats "I went to the grocery store and bought..." whatever player 1 said and something that starts with B. You keep taking turns til someone forgets or messes up the list, and go all the way to Z. It's a memory game.
