You cannot Special Summon monsters the turn you activate this effect, except WATER Monsters. During your turn: You can shuffle 1 "Ice Barrier" monster you control and 1 "Ice Barrier" monster in your hand or GY into the Deck, and if you do, Special Summon 1 "Ice Barrier" Synchro Monster from your Extra Deck, whose Level is equal to the combined Levels of the shuffled monsters. (This is treated as a Synchro Summon.) You can only use each effect of "Frozen Tundra of the Ice Barrier" once per turn.
As some people are probably aware, I am a big ice Barrier fan. Unfortunately, they aren't exactly good, especially in today's age, even with the new support, although they are better than before. which is a shame as they have some powerful cards, and beautiful artwork. Now, while I'm pretty sure this card won't make them meta, I'm hoping it would at least give them a slight boost to their power level and ceiling. Mind you the PSCT is probably off, but I was trying to make the second effect be kind of like starlight junkons quick-synchro effect, but slightly different. Anyway I hope this card helps, that's for sure.
