I posted basically the same version of this on the Destiny Hero Deck Recipe page because I've seen someone named Edo who seems pretty knowledgable post one, and I hope to get his advice. But since yoy asked, here is D-hero f2play version:
Is two econ okay? Or do you recommend one more? Also, is it possible for plasma to come out quickly if you are still focusing on fusion, too. I like dasher, because I can get him out quickly, but plasma just looks so tempting.
d-fusion build is only worth if you have more than 1, otherwise stick to vyon. Plasma wouldn't fit the variation i mentioned as well as Dogma, both can be obstacle in activating - celestial draw if you are stuck with them in your hand. d-fusion is amazing card, that allow you to counter so many things, and makes your destructive guy indestructible to removals/battle dmg during your opponent turn.
there is a deck i played against during kc stage 2 that utilize Plasma: https://www.youtube.com/watch?v=WZy0E_yJ_bA
based on tokens, though the one i fought also used mystic boxes. btw the combo of the d hero setup i mentioned is to dump celestials/dreamers with destructive guy ability, during your or opponent turn to GY, to absorb dmg or summon dreamers from GY as materials for d-fusion.
I'm trying a non-fusion build for a while, so I'm going with two d-cubed and the ones that special summon easily like dreamer and fearmonger. If I go back to trying a little fusion, it will be Vyon with one polymerization. What about Aster's lv. 40 reward destiny draw?
tried to replace 1 d-fusion for destiny draw but i feel like deck works better with more protective traps and with destructive guy+celestial draw combo you don't really need to care about more draw, or rather care to don;t mill yourself! lol. malicious can be substitute for dreamer, for d-fusion, so if you don't have 3 dreamers you can try to replace them.
honestly, is not worth to build d-fusion deck without 2 dangerous, trinity is very situational used only for otk and dangerous is bread and butter of this deck. if you have only x1 then you want to focus on trinity maybe with anti-magic arrows. there is example of deck im currently use, another d-fusion instead d-draw works better, about 60%+ winrate in plat, though this deck wont go up to kog.
