I'm not gonna try to attempt to go into every card and how its a good/bad/fucked-up change to the game, everybody is doing that and you should have already known by now what these changes will do. Trishula coming back to the game really makes me wanna play Mermails, problem is I'm no longer in Malaysia and my playset of Trishulas aren't legal here in the US. Besides, I already know which deck to build here once I've settled down, obviously, with Emergency Call coming back to 3 and Mirror Force to 3, I am gonna build HEROs.
I don't like Pot of Duality in HEROs, the deck is consistent enough without it and it kinda slows it down.
I'm not sure how viable Firefist is gonna be with Tenki at 2 and Rooster at 1, but I'm sure Mermails will definitely be one of the top decks as of now. The deck has can make Trishula with 1 card, what did you expect? Ophion will still stand as one of the top decks since it didn't get hit in anyway and its worst match up Firefist lost some consistency.
Thats my reaction to the banlist. Sorry for such a short post, I'm still trying to get used to the US. If anyone knows where YGO players meet in Denton, TX, please let me know.
