Before Kaladesh, the Blue-Red Fevered Visions deck was quite popular, and it has been known to have solid matchups against midrange strategies. The deck hasn't seen much play recently, but expect that to change after the deck had a breakout performance this past weekend.
It may seem weird to have a spell-based deck and not run Thing in the Ice, but I approve of the choices Jonathan made in regards to creatures. The deck is primarily burn and interactive spells, so there can't be too many creatures in the deck. Thermo-Alchemist is perfect because it can block on occasion, but when played on turn two it can deal a ton of damage over the course of the game. There are only two different creatures in the main but they come down early, and are great when left unanswered.
The best plan in most matchups in the first game is to have an aggressive draw backed up with an early threat like Fevered Visions or Chandra, Torch of Defiance. The Bedlam Reveler plan after sideboard really is a nice innovation. There will be times when this deck wants to primarily hold answers and take out the Fevered Visions to be more controlling. Bedlam Reveler is a threat itself, but drawing three cards is a lot of card advantage. In the recorded matches, we saw that we were able to successfully grind out White-Blue Flash this way.
A lot of the matchups in this format feel good for the Fevered Visions deck, as long as we get off to a good start, which sometimes isn't easy. The White-Blue Flash matchup went smoothly since we were able to set up every turn and manage the flash creatures effectively. Against the other major deck right now, Black-Green Delirium, Fevered Visions as a deck looked much less impressive. These were games where our draws were not great, and we didn't play Fevered Visions on turn three. While this is bound to happen, I believe in retrospect my keep in game two was too greedy, so I blame part of the loss on myself. The loss here felt more due to bad draws than it being a bad matchup.
In fact, more often than not the Blue-Red Visions deck should beat Black-Green Delirium, as Jonathan did through the Grand Prix in Santiago. We played against two of the major decks in Standard, but then came up against a rogue deck. While energy-based decks are certainly in existence they are not particularly popular, so it was fun to play against one. The games were definitely close, as Decoction and Fabrication Module out of the Temur Energy deck help provide an impressive lategame. Aetherworks Marvel, however, was much less impressive in that deck as compared to the dedicated combo deck. Not needing to worry about the possibility of a huge eldrazi coming into play was nice.
While Jonathan did well with the deck there are some potential changes that could be made. For instance, adding more blue mana sources definitely would have made a difference, as not having blue mana early was a real issue in some of the games. With a couple minor adjustments I expect this deck to evolve into a legitimate option in this Standard format.
