So essentially, Combustible Gearhulk is a 6/6 first strike artifact creature with an ETB that draws you 3 cards, for 6-cmc
Energy acceleration is a great example of such a plan, Welder and Magma Basin are great Energy accelerators, and Charizard VSTAR is a very good attacker, so play these cards together and you have a solid deck
