My version of Temur Pummeler*
Use Trophy Mage to tutor Pummeler - or Tower, if you're against a control or burn deck, as the many energy-generating creatures and energy Tower gives you for your instants and sorceries make for an easy reliable bolt-tower as an alternate wincon. I was using Rogue Refiner, but found that tutoring the wincon was much better than a random draw and 2 energy. When Slip Through Space (great for making your many creatures that can get crazy-big unblockable, and the draw is really useful for this deck) and Uncaged Fury (no explanation needed) rotate out, I plan on replacing them with 4 Cartouche of Knowledge for the draw and evasion, 2 Larger than Life, and a Driven/Despair, because the buff and Trample make for good replacements of Double Strike.
(Like every Green Energy deck)
Cub and Hydra can ramp to big size, so having them to deal with while you build up energy for Pummeler or the tower keeps your opponent busy, and Attune, Hub, and Servant for mana fixing mean you can reliably cast Brawler turn two, and have the Blue for Trophy Mage and Slip Through Space.
Let me know what you think, all suggestions are appreciated!
*Made this deck when it was Standard legal, now changed it a fair bit for Pioneer so parts of the description are no longer accurate, but I enjoyed the nostalgia of reading it, so I'm leaving it as is ✌
