In the case of Genetic Apex, the first card set for TCG Pocket, your choices are between three classic Pokmon - Charizard, Pikachu and Mewtwo
(Don't apply Weakness and Resistance for Benched Pokemon.) Attack 2: [3] Destructor Beam (90) Flip a coin
Maybe there's another Blazing Shoalbased deck or combo that could be scary, although it seems like it would have the same problem as Shoal Infect (needing to play a bunch of expensive, uncastable cards to make Blazing Shoal work)
Many of the cards for sanctioned paper Vintage are outrageously priced (although you can get them for much less if you're willing to bend on condition considerably)
Well need a wide board to win the game, so one thing the deck really wants to do is spill as many Wolf tokens into play as possible before we go for the big win
You can also try to create synergies within your own deck, whether it be with Deaths Shadow as mentioned above, or my personal favourite in Legacy of casting it at your opponents end step and then cast an Uro, Titan of Natures Wrath a three-mana 6/6 creature
