I tried a version of this deck with a couple Tridents, as mentioned earlier in this thread, and it worked a lot better. Having the Trident not only annoys people (I've had a LOT of people rage quit against me when I play my Graboid Rainbow...they really hate Quicksands), but it also gets rid of the Eternity stall that rainbows use. If they play through most of their deck with Hourglasses, then
will likely be quite limited near the end of the game, making it quite easy to cut off their supply with a Protected Trident.
I only managed to play a couple games before dying of boredom and switching back to my normal PvP deck, lol, but it was fun while it lasted. I only have 5 SoGs, so I added an extra SoD to make up for it.
