Me Vs An Mono Electric

I got a god hand. 2 hitmonchan,4 fighting, 1 dbl colorless. he sends a pikachu and evolves it after i place my hitmonchan and put a rock energy but i decided to pass my turn. he uses thunder but fails and i jab. he then switches raichu for zapdos. i place another rock on my hitmonchan.he places another thunder energy.I get dbl colorless on hitmonchan and i used special punch. zapdos is almost dead but he uses super potion. after a couple of turns he lost for forgetting to put prizes ( i didnt notice earlier cause when i killed his zapdos i didnt see prizes)

Me Vs water/grass

Unlucky for me i heard this deck of my friend had 2 gyrados and i had no pokemon who could beat it. luckily i get a jynx and 2 psychic and 2 dbl colorless and electabuzz and lightining energy. thank god my friend had no basic in deck so i draw 2 cards ( super energy removal and a chansey) then my friend had a magikarp and thats it haha.

finals
