Sketchy Goblin

When Sketchy Goblin enters the battlefield, using a No.2 pencil, write down one keyword ability in its text box below.(Ex. Trample, flying, haste, etc.) Sketchy Goblin has that ability as long as it is written in its text box. Any abilities with a cost or number following it must always result in 1.(Ex. Annihilator 1)
