I have a question about pot of avarice.It says you can add five monsters back to your deck.Do you have to add five or can you
add up to five.Thanks.

THis is the rulings:
"Pot of Avarice" targets 5 monsters in your Graveyard. You cannot activate it you do not have 5 or more monsters in your Graveyard.
If any of the 5 monsters targeted by "Pot of Avarice" are removed from the Graveyard before its effect resolves, for example by "Disappear" or "Call of the Haunted", then the entire effect of "Pot of Avarice" disappears. You do not shuffle the other monsters into your Deck and you do not draw 2 cards.
You can target Fusion Monsters in your Graveyard for "Pot of Avarice" and they will be returned to your Fusion Deck.
You can chain "Serial Spell" to "Pot of Avarice". You select 5 targets for "Pot of Avarice", and then when you chain "Serial Spell" you must select 5 targets. You can select the same monsters, but if you do this then "Serial Spell" will resolve first and shuffle some monsters back into the Deck, and then when the original "Pot of Avarice" tries to resolves, there aren't enough monsters left so it will not resolve. Monster Cards you discard from your hand for the cost of "Serial Spell" can be selected as targets for the "Serial Spell" copy of "Pot of Avarice".



So in short, there have to be five monsters for it to activate and resolve.
