Mew Prime has a Poké Power, See Off, that allows it use the attacks of any Pokémon in the Lost Zone. Cool Porygon has an attack called Texture Magic: "You may change Cool Porygon's Resistance to a type of your choice other than Colorless. If the Defending Pokémon has a Weakness, you may change it to a type of your choice other than Colorless. (Benching either Pokémon ends the effect on that Pokémon.)"
In Unlimited, what happens if Cool Porygon is in the Lost Zone, and I decide that Mew should use Texture Magic? Mew has no resistance. Can I give it a resistance of my choice anyway, or would it have no effect on resistance (but I could still change the opponent's weakness), or would I be unable to use the attack at all?
Thanks a lot!
That's a good question. Based on how I understand it, you can change the Resistance when using Mew Prime's PokePower "Lost Link" (See Off is the name of the card's attack that lets you put Pokemon in the Lost Zone) -- before taking my answer as the final word, I'm going to go ask the rules team if they can provide an answer for this scenario.
