Okay, I will change the second attack, but I still think it is a cool attack other than bending the rules. I think it is okay to use an attack other than Shadow Rush in Hypermode if there is drawback.
Is it okay then to evolve a Shadow Pokemon who is in Hypermode after all the attacks were unlocked? If so, then the Hypermode condition will be removed, right?
Shadow Xatu (P)
80HP
Stage 1 (Evolves from Natu)
Shadow Psy (P) (turn 1)
Flip a coin until you get tails, for each head, put one damage count on the defending Pokemon. If the first flip is tails, Shadow Xatu activates its Poke-Power: Hypermode.
Evil Psy (P)(P)(C) (turn 3) 40+
Flip a coin, if heads, You may use this attack instead of Shadow Rush if and only if Shadow Xatu is in Hypermode. Put one damage count on Shadow Xatu. If the defending Pokemon is a Shadow Pokemon, it is now in Hypermode. If the defending Pokemon is not a Shadow Pokemon, this attack does 40 damage plus 20 more damage and put one damage counts on Shadow Xatu. If tails, this attack does nothing (not even damage).
Shining Psy (P)(P)(C) (turn 3) 40
This attack can only be used if Shadow Xatu is not in Hypermode. If the defending Pokemon is a Shadown Pokemon, it cannot activate its Poke-Power until the end of your next turn. (this effect will not be removed even if the defending Pokemon is benched) If the defending Pokemon is not a Shadow Pokemon, you may remove up to 2 damage counts from Shadow Xatu.
Weakness: (P)
