I wanted to maximize triton's mobility with sunken tower and fanatic. Tactician was chosen ahead of Trainer because it's sturdier. Not many big creatures on ladder at the moment so attack doesn't matter as much, and 1 humbling vision was cut for the third tower. You can consider other tritons like Ninja Toad and Tower of Curses too.
This deck is pretty fun to play, allow for full board control in some games, but probably not optimized. I made god rank with it this season. I didn't consider banquet because it's broken.
