Haste When this creature enters, create a colorless artifact token named your choice of A, E, I, O, or U. Whenever this creature attacks, using the first letters of the names of permanents you control, spell a word you haven't spelled this game. It gets +1/+0 until end of turn for each letter in that word.

When this creature enters, you may put a name sticker on it. Add {R} for each unique vowel on that sticker. (The vowels are A, E, I, O, U, and Y.)

The Space Family Goblinson has trample as long as you've rolled three or more dice this turn. Whenever you roll a die, put a +1/+1 counter on The Space Family Goblinson.
