I was thinking it'd benefit Mega decks a lot too. We can slap Spirit Links onto any Basic now since they carry over after swooping, and essentially evolve into the Mega immediately.
If the next Pokémon does not have the Theta Double ancient trait, you have to discard 1 Pokémon Tool Card, that's obvious.Ninja Boy is the card that finally makes Ancient Traits strong! You want to set up a benched pokemon with 4 energy but dont want it getting Lysandre'd during setup? Set up Omega Barrier Electrike and then Ninja Boy it for your Golem-EX once done.
You want to put 2 fighting fury belts on your Emboar-EX so it has 260hp and hits for 170? Ninja Boy it out from your Theta Double Entei with 2 belts attached.
With this and the new Volcanion-EX i think Entei decks are going to be absurdly strong in the future.
If the next Pokémon does not have the Theta Double ancient trait, you have to discard 1 Pokémon Tool Card, that's obvious.
The rules of this trading card game say that a Pokémon card can hold only 1 Pokémon Tool card. Theta Double lets you attach 2 Pokémon Tool cards. If a Pokémon card does not have this Ancient Trait or loses it, it can hold only 1 Pokémon Tool card as usual, so you have to discard 1. Yes, I think it's pretty obvious...sorry, is that obvious? i mean i dont think being able to ninja boy out for 2 tools makes much sense either but it just seemed to not have any info that says what to do in the situation, not like a card like strong energy for instance when used "incorrectly".
