Here's a quick tip for your deck. It needs to be able to tell a story. If you can't sum up your deck in one or two sentences, it's too unfocused to be functional. Here's what my statement would be to describe the deck: "It's Naya aggro with bolster to reach
Mayael's Aria as a win condition. It also has Dragons for power houses and attacking. There's also a little burn.
Assemble the Legion is in there to create tokens. Mana dumping is put to a
Heroes' Bane, while Mana Excel goes to Mayael, even though there's only one copy of each. Field control is also present."
See how that's just a little scattered?
This is one of my decks right here:
https://deckstats.net/decks/25317/166513-trial-by-fire/enThis would be the statement for it: "
Trial by
Fire destroys everything on the field, so that Havengul and Hissing can
deal damage repetitively alongside a returning
Flame-Wreathed Phoenix. "
There's not a lot of screwing around in my deck. It's kill and damage, that's the point of the deck. What I'm trying to say is that your deck doesn't really have a point to it.
Mayael's Aria is your potential win-condition, but there's not enough support for it, a lot of deck space goes to random things that don't make sense.
