My Evil Sylveon

I challenged myself to make decks out of the Stage 1 Eeveelution promos we got during the Sword & Shield block, without using any of the multi-prize Pokemon avalable in expanded.

If you opponent starts out with a fat, slow attacker without a way to accelarate engergy or switch, you're guarneed to be ahead in the prize war before the match even starts, by stalling out with Time Out Kick. The 2nd attack is identical to the one on Eevee V's promo, except Silveon gives one less prize on knockout, in exchange for doing 20 damage less when powered up with a supporter.

A major flaw in this deck is that if you loose momentum, its very easy for your opponent to turn thing around. The heavy reliance on trainer cards, especially supporters, can also be exploited by your opponent with little chance of counterplay.
