Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During your Main Phase: You can place this card you control and 1 "Centur-Ion" monster from your hand or Deck, except "Centur-Ion Trudea", in your Spell & Trap Zones as face-up Continuous Traps, also you cannot Special Summon "Centur-Ion Trudea" for the rest of this turn. During the Main Phase, if this card is a Continuous Trap: You can Special Summon this card, then you can increase its Level by 4. You can only use each effect of "Centur-Ion Trudea" once per turn.
