Artifact Creature - Golem 0/0, 6 (6) Modular-Sunburst (This enters the battlefield with a +1/+1 counter on it for each color of mana spent to cast it. When it's put into a graveyard, you may put its +1/+1 counters on target artifact creature.)1
Illus. Christopher Moeller
12/1/2004: This card has modular--sunburst, a combination of two keyword abilities. The sunburst ability sets the number for the modular ability. Basically, the number of +1/+1 counters the Wanderer gets as it enters the battlefield is equal to the number of colors of mana used to pay its cost.
12/1/2004: For the leaves-the-battlefield ability, the number of counters on Arcbound Wanderer at the time it left the battlefield is what's relevant; the number of colors of mana used to pay its cost doesn't matter anymore.
12/1/2004: When the Wanderer leaves the battlefield, you may put the counters onto a single target artifact creature. You can't split them among two or more artifact creatures.
9/25/2006: If an Arcbound creature gets enough -1/-1 counters to make its toughness 0 or cause the damage on it to now be lethal, the Modular ability will still give another artifact creature a number of +1/+1 counters equal to the number the Arcbound creature had before it got -1/-1 counters.
