A few small tweaks and additions. Trying out Breya's Apprentice in Scrap Heap. This format really needs cards that fill multiple roles for a given theme. Apprentice is two artifacts, a sac outlet and card draw all in one. Subbing it in for one of the bombs should give a more consistent game plan. And speaking of Combustible Gearhulk, that went over to Chaos, which was in need of a couple more good stuff cards.

Scion of Draco looks so crazy cool for the Rainbow deck. Happy to have a payoff for playing all five colors rather than just a bunch of efficient multicolored spells. I also like that it will buff creatures in partner decks. Cross-deck synergies are very valuable.
