Use cards instead
All you need is three cards, one for each attack. Each round you pick one card to determine what happens. All you need to do to take out the tail attack is put that card aside until the end of the round.
Cards can be easily made at home, either by writing them out onto index cards old-school fashion, or printing them. A side benefit of this method is that you could put extra details of the attacks (damage, to hit, whatever) directly on to the cards rather than needing to look them up.
