Forum:Psi-Station

When I normal summons a Psychic-Type monster, can I activate the effect of Psi-Station only once or any number of times? For example, I normal summon Krebons, can I pay 5000 life points to make it a level 12 monster with 4200 ATK? Nephthy (talk • contribs) 14:06, July 7, 2012 (UTC)
