Yes, cards with simple effects like Hey, Trunade!, Needlebug Nest, Restructer Revolution, Invoked Magellanica or Amazoness Swords Woman will also never get limited because they also have simple effect. That's a fact.
Restructer Revolution was a flak, just like restricting Woodland Sprite.
With the meta today, and the Cup of Ace limit-2, no one can pull of Restructer Revolution.
Don't worry. Komoney will release this card in a box that will have new supports for Axe Raider. That way you will feel obligated to buy 3 copies of Axe Raider.
The problem with Blizzard spell card is not that its that thrash like everyone say, it can win you a turn, which is often enough to turn the duel for your favor, but yeah its a tech card right now and not worth a pernament sloth, maybe if we had side decks, then it would be a good side deck card.
