This is by far the most important step. You will need:
5 x Centaur Warrunner(s)
If you get unlucky try drafting again in 30 minutes.

Get ready to whoop some ass
After you get matched be a good sport and send a 'Good Luck' line to your opponent from tower menu

By now your opponent will have realized what sort of a monster he/she is facing and might ask questions.
Do not say anything.

Pass the first round without playing any card(s) to lull the opponent into a false sense of safety

Now that the opponent no longer sees you as a threat it is the perfect time to strike. You will need to:

1.Put your 4th Centaur Warrunner into a lane where another Centaur Warrunner is currently unblocked and has a creep next to him blocking the enemy hero so you can hit the enemy tower with TWO Centaur Warrunner(s). /preferably in the last lane for the maximum shock effect/

2.Pass the other two lanes without playing a card as a show of faith.

3.Now that your opponent's resources are exhausted on the other two lanes they won't be able to play spells or creep on the third lane (trust me)

4.I forgot to mention you need 4 of these amazing cards [shown on the right]
on the second turn in your hands
but you are guaranteed to have 4 or
more because you have 15 of them
in your deck.

5. Use 2 Double Edges on each Centaur
respectively and watch the opponent's
tower health flash 40-40

Losing an entire tower on the second round of the game is unheard of and your opponent will have lost their motor functions from shock and will be rolling around on the floor like an astrazeneca victim. 99% of players would surrender here [or so i imagine]

If the opponent has not surrendered already and the game continues onto the third round, simply repeat what you did last round with your FIFTH Centaur Warrunner in the first or second lane, you will draw two more cards to be added to your existing three cards now totalling FIVE, four of which are GUARANTEED to be Double Edge(s)

Oh and your opponent might be prepared to foil your plans this time around so ask them if they have any spells or creeps before using Double Edge on your Centaur(s)

I hope you win your games using this strategy.
