Surge Node enters the battlefield with six charge counters on it.
{1}, {T}, Remove a charge counter from Surge Node: Put a charge counter on target artifact.
Once Surge Node has run out of charge counters, it remains on the battlefield.
Surge Node can be the target of its own activated ability. Because it doesn't “move” a counter, the ability will remove a counter from Surge Node and then put one onto it.
