A word of warning however
An example is a card with a missing portion of stock, such as when a card that was meant to be hand cut falls below the published measurement tolerance, like an early 20th century strip card
It blocks very well the turn it comes into play, and it also eats up a Lightning Strike or a Wizards Lightning, keeping your bigger threats safe for yet another day
In general, the answer is going to depend on how much your card is worth, and whether the value is likely to go up from a good grade
The charge counters can come from any source
While this cards pack tactics ability is certainly nifty (gifting you a free 1/1 Gob if your attacking creatures powers are equal to six or more), its this cards one red and one colorless activated ability that truly shines: being able to give haste and a healthy boost to all of your Goblins powers can sometimes end a game (for one player, at least) on the spot
