If you have two tentacools and an Alakazam on your bench, try to get a Chansey or something with high HP and a high damage rate as your active Pokemon. If the defending Pokemon does any damage to your active Pokemon, use damage swap and swap the damage to the tentacools, 2 on each. Then use Pokemon Power: Cowerdice, pick them up in your hand and put them back down on your bench with no damage on them! Keep doing this until your active has enough energy on it to blow your opponent away!
