Good Goblin Houskeeping

can someone explian a little bit about how this card should be used exaclty.

Card Name: Good Goblin Houskeeping

You draw 1 card when you activate it if you have 1 in grave you draw 2 if you have 2 you draw 3 cards its like that trap that allows you to draw a card exept with this onee you can draw up to 3 cards

Which part of the effect you don't understand?You just draw one card and then after you draw return whatever card you want on the bottom of deck [since in KCVDS there is no such option "return card on bottom of deck] so you just shuffle the deck.If you have 1 or 2 cards with the same name in the grave then you draw 1 or 2 additional cards and return one in deck.

thanks guys, the only thing that i didn't understand back then, is what if i dont have any other copy in my grave .. do i draw 1 card or draw nothing .. but now every thing is clear .. thanks
