Hello!
I can Say devoing or even evoing epic heroes is a pain, getting the extra copies you need is very grinding and takes hundreds of thousands of gems to get one that you need, so I want to suggest epic shards, basically they're regular shards, but orange instead, they can be used to evo devo and upgrade relics for epic heroes, you can buy these or get them in prestige shop, the cost to evo and devo are about double then regular heroes(40k for Evo, 120k for devo,) These shards can also be used to upgrade epic hero relics (like I said earlier), I'm pretty sure I've covered everything, Thanks for reading!
570k(might forget to change sooner or later)
Free to play
Hmm...what else to put here...
Turkey!
