Single Strike single prizers ft. Skwovet/Altaria

There are no pre evolutions for Beedrill, (Kakuna and Weedle) Cinderace, (Raboot and Scorbunny) and Emboar (Pignite and Tepig).

You could possibly use supporters for discarding instead of pokemon as they are useful in other ways and discardable too.

Or if you have other problem with this method cards like Radiant Greninja's Concealed Cards or Kirlia and Gardevoir's Refinement ability can let you draw cards and discard cards you dont need at the time. 

Keep in mind that some drawing cards are type specific like Radiant Greninja. 

Cards like Forest Seal Stone, Single Strike Scroll of Piercing, and Battle VIP Pass can be taken out as they are not that useful to the deck.

Also your heroes of the deck (Urshifu and Sirfeched) are low hp and there are to little cards to consistently keep them in play and do damage properly without attacking with compatible support pokemon (Abomasnow and Houndoom) and those pokemon suffer the same issues as listed above.

Another flaw is that there are no basic energy so this deck can easily be countered by Duraludon Vmax and cards like that.

I don't see enough strategy in this deck and it is not worth the cost. 

Instead of Abomasnow you could use Choice Belt and Single Strike Mustard is unnessicary

I think you may have missed the point of this deck. It is build so that each turn, you use Altaria's Tempting Tune ability to put a supporter card of your choice on top of your deck (usually Single Strike Mustard) then you use Skwovet's Nest Stash ability to shuffle your hand and put it on the bottom of your deck and then draw into the supporter you placed ontop of the deck. If you chose Mustard as your supporter, you can instantly search out any single strike Pokémon (even an evolution Pokémon) and put it onto your bench.

I have plenty of other supporters like Professor's Research and Arven that can be searched out in the same way as Mustard.

I did not want to put in Radiant Greninja, because it discarded valuable energies or Kirlia because it was an evolution Pokémon.

I already have a mini drawing engine in Skwovet-Altaria, which I can use to search out any supporter.

Battle VIP pass is necessary to set up Skwovet, Swablu, and Houndour (all vital cards to my mediocre strategy)

Urshifu and Sirfeched are not meant to stay in play more then one or two turns, but the opponent will have to knock out quite a few of the because they are only worth one prize card.

3 copies of path to the peak can counter Duraludon.

This was one of my first decks on this site, and I was just learning about the TCG (meaning it does have a few flaws).

Lastly, this was meant to be an experimental deck, not meant to be used in any sort of major tournament.

Sorry if i came on hard

but i still think maybe basic energy and more copies of urshifu will be vital
