Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control an "Ice Barrier" monster, you can Special Summon this card (from your hand). You cannot Special Summon any Level 5 or higher monsters the turn you Summon this way. You can Tribute this card, then target 1 "Ice Barrier" monster in your GY, except "Prior of the Ice Barrier"; Special Summon that target.
