After having much success with BG Energy Aggro, I decided to look at adding Blue for 4 mainboard cards (1 an artifact but discussed below) and a few good sideboard cards. The idea was to still keep the Constrictor / Ballista combo as well as some other key pieces to be able to apply pressure as well as keep good synergies in the deck. The basic plan is +1/+1 Counters, Card Advantage, and Use of Energy.
The 4 main reasons I wanted to add blue:1. Fabrication Module: Although there is only 2 in the deck, if you manage to get one out, there is a good supply of energy to give a boost to a creature. With a Constrictor on board, things can get out of hand very fast.2. Empyreal Voyager: Although the 2/3 body does not look that great for a converted 3 mana cost, the fact that it has flying and trample is no joke. The added bonus of gaining energy from damage synergizes well with the rest of the deck. It does avoid staple removals in the new meta with shock and fatal push (unless Revolt of course). I understand it is underwhelming against a Heart of Kiran, Harvester, or Mindwrack, if it remains on the board it would be able to catch up very fast (Rishkar, Fabrication Module, Verdurous all combined with Constrictor).3. Skyrider Elf: Digging deep back into BofZ for this gem. Worse case scenario you have a 3/3 Flyer on turn 3 or with a Constrictor turn 2 you have a 4/4 flyer turn 3?!. Converge is so easy with this deck with the number of dual lands, aether hub, and servants. Although it doesn't pass the fatal push test, shock won't hit it and it is a flying body in the air against Mardu Vehicles.4. Rogue Refiner: 3/2 for 3 but, the energy and card draw is such a bonus.
SIDEBOARD:Needing some help with this but, my idea would be to have a couple of Altered Ego's (for Control and Even the BG match up), Rashmi, Eternities Crafter (Great card advantage), Negate, Dispel, Verdurous, Heroic Intervention, and another Fatal Push.
I believe everything else in the Mainboard are pretty self explanatory (Glint Sleeve for card advantage and energy sink, Bristling Hydra for energy sink).One card I should mention, Greenbelt Rampager is a great utility card. Early game you get a 3/4 on turn 2 for 1, or you can return it to your hand to trigger Fatal Push on larger creatures, or bounce late game with a Fabrication Module out to produce counters.
Suggestions are welcome.
