Officiele rulings

1/1/2011
As Ratchet Bomb’s last ability resolves, its last existence on the battlefield is checked to determine how many charge counters were on it.

1/1/2011
Ratchet Bomb’s second ability destroys only those nonland permanents whose converted mana cost is exactly equal to the number of charge counters on Ratchet Bomb. It doesn’t matter who controls them.

1/1/2011
If Ratchet Bomb’s second ability is activated while it has no charge counters on it, it will destroy each nonland permanent with converted mana cost 0.

1/1/2011
The converted mana cost of a permanent is determined solely by the mana symbols printed in its upper right corner, unless it’s copying something else (see below). The converted mana cost is the total amount of mana in that cost, regardless of color. For example, a card with mana cost 3UU has converted mana cost 5.

1/1/2011
If a permanent is copying something else, its converted mana cost is the converted mana cost of whatever it’s copying.

1/1/2011
In all cases, ignore any alternative costs or additional costs (such as kicker) paid when the permanent was cast.

1/1/2011
If the mana cost of a permanent includes X, X is considered to be 0.

1/1/2011
If a nonland permanent has no mana symbols in its upper right corner (because it’s a token that’s not copying something else, for example), its converted mana cost is 0.
