Magic the Gathering - Can you tape someone's creature before their attack phase?

ok, make sure you and your friend keep in mind that the magic card game is different from the xbox and online versions, and since you're playing the card game, you should follow the card game rules, so your friend's point is moot. also, if you can use a card or effect to tap his creature, you can do it in the card game, no matter what the x box and online versions allow. you can nly use lands YOU control. i suggest you get a copy of the magic card game rules before playing any more maagic games.
