Only slightly, with the Eeveelution sitting around $1050
If you're sticking to the Vampire Aristocrats theme then the first cards I'd pick up would be Vampiric Tutor (finds Skullclamp and has Vampire in it!), Bloodletter of Aclazotz which doubles your drain / damage output on your turn absolutely wild, Bloodline Keeper provides sac fodder and a strong anthem, Legion's Landing nice thematic ramp, and Sorin, Imperious Bloodlord thematic ramp and removal
For those new to Pokemon TCG, the variety of Pokemon types like GX, V, Tag Team, countless cards, and more may seem overwhelming
And then I can cast something good for four mana
