Spoiler: Entry [Basic] Deoxys GX – [P] – HP190 Ability: Wow! Signal When you play this Pokémon from your hand onto your Bench during your turn, you may put any amount of Energy attached to your Pokémon in the Lost Zone. Put one Alien Virus counter on each Pokémon that doesn't have any Energy attached to it for each card put in the Lost Zone in this way. The attacks of Pokémon with Alien Virus counters cost [C] more for each Alien Virus counter on them. (If a Pokémon evolves, remove 1 Alien Virus counter from it.) [C] Close Encounter This attack does 30 damage to each of your opponent's Pokémon for each Alien Virus counter on it. Also apply Weakness and Resistance for Benched Pokémon. If a Basic Pokémon (except for Pokémon-GX or Pokémon-EX) would be Knocked Out by damage from this attack, that Pokémon is not Knocked Out and its remaining HP becomes 10 instead. [C][C] World Ender GX Knock Out each Pokémon that has any Alien Virus counters on it. Neither player can take more than 2 Prize cards during the turn you use this attack. If this Pokémon has 60HP or less, this attack does nothing. Weakness: [P] x2 Resistance: - Retreat: - GX Rule: When your Pokémon GX is Knocked Out, your opponent takes 2 Prize cards. Spoiler: References Tapu Lele GX Blacephalon GX Head Ringer Focus Sash Espeon PLF Spoiler: Thought Process I tried to go for a card that had a lot of decision-making involved for both players, reflected by its ability and attack. Do you sacrifice more Energy to get more counters? Do you not evolve your set up Pokémon in order to avoid potentially being Knocked Out, or is getting an important KO more important? How many of your own Pokémon do you infect? On to the card itself, I chose Deoxys because it's one of my favorite Pokémon. The Ability and attacks are like a possible sequence of events of alien contact, the first being the famous wow signal , followed by the actual first encounter, and then by the plot of every alien sci-fi movie ever. It's important to note the Ability interacts even with Deoxys itself, so the attack costs have been balanced around that. You could not use the ability and have super small attack costs, but then the attacks would do nothing. Going first, you can use the Ability to mark all of your opponent's Pokémon, although without any Energy acceleration most of your counters will be gone by your next turn, so you can't just dunk your opponent then (the first attack also has a built-in non-dunking, punishing only big basics.) Then again, you might just be adding 30 more damage to your own Pokémon if your opponent has a Deoxys of their own. The GX attack has a lot of restrictions as to not make it an insta-win, but not so obnoxiously hard to achieve that it's unplayable. The HP restriction is there partly alluding to the fact that an alien machine would need a lot of resources, but also as to not make it super sacky that you get into a 'might as well GX attack' situation that swings the game completely into your favor. I'm overall pretty satisfied with how the card turned out (after going through many iterations of it) but it I'm not 100% sure about all the numbers.
