Forum:Possible Battle Teleportation OTK?

Required Cards:

Battle Teleportation

Hyper Psychic Blaster

Psychic Snail

Vengeful Servant

On the field = Hyper Psychic Blaster equipped with Vengeful Servant.

Turn 1= Set Psychic Snail and Battle Teleportation

Turn 2= Activate Battle Teleportation and target Hyper Psychic Blaster. Flip Summon Psychic Snail and activate its effect to allow HPB to attack twice. Enter Battle Phase. Attack directly with HPB twice. End Battle Phase and by Battle Tele's effect, HPB goes to your opponent. By Vengeful Servant's effect, they take damage equal to the equipped monster's attack for game. (3000 x 2 + 3000 = 9000)

Ruling Question Battle Teleportation states that "If you control only 1 face-up Psychic-Type monster..." then you can activate it. But does the above scenario qualify for the activation and use? Before Battle Tele activated, Hyper Psychic Blaster WAS the ONLY FACE-UP PSYCHIC type monster on my field. Snail was still set and therefore didn't count towards the number of Psychics on my field. And if it does qualify, after Flip Summoning Snail, will Battle Tele's effect stop or am I able to do the above theoretical OTK/2TK?
