No Spiral Fusion LOL. On the positive side if your F2P it's better for the spiral fusion to be in a mini box than in a structure deck since it means you can actually get 3 copies.
I disagree. With Google Rewards, you can get enough free dough to buy Structure decks when they are put at half-price. With the added bonus of getting all of its cards for sure.
Most F2P players are casual players. Which means they also don't have enough time to complete requirements for Google rewards. Although this is true if your using google rewards.
