We're On A Tight Budget

You and you opponents can't cast spells
that don't have the title "We're On A Tight Budget" with converted mana cost 5 - X were X is the amount of "We're On A Tight Budget"s are on the battlefield
At the beginning of an upkeep any player may tap all their lands and pay {5}+X. If they do, untap all land that player controllers and destroy all cards with the title "We're On A Tight Budget".
