Long time listener first time caller! I'm a janky deck fanatic and love to brew my own decks that will barely squeak into plat 3 but will be an absolute blast.
Rolant's memorial is a potentially bonkers card and after browsing eternal war cry, it did not look like anyone really tapped into it yet. The key here is to get a bunch of discard abilities, to discard your echo cards(producing card advantage and giving you solid discard options. Meanwhile if you buff up an
Acquisitive Crow,
Geomar, the Steel Tempest,, or
Rilgon's Disciple. heck even a spare
Cliffside Porter, it can be GG pretty quickly.
The key here from what I have found is not to rush out
Rolant's Memorial, it can set you back on turn 3 especially when it doesn't have enough in the void to ramp up. By the time you have 5 or 6 spells in the void, that is the perfect time to pop that baby in there.
This is super janky and typically unexpected. I would love any advice you have to make this Rolant/Discard deck even more efficient.

I would look at playing Whispering Wind. It is a 2 drop (good), it has flying (goood), it has discard (gooood), and it synergizes well. If you use her to dump a unit from your hand you get to A) dump a unit, B) draw another card from your deck which could help you get your better cards, and C) she will activate Rolant's Memorial and you can use it to buff her making her a big beefy flyer.
I would also consider Kosul Battlemage since he also buffs with spell use, he's a 3/3 on 3 with aegis (which is really great as well).
Also, if you have her, I think Svetya, Orene of Kosul would be a better card over Yeti Troublemaker as she helps you control the game some more, has potential discard synergy, and just overall will help you out IMO.
Finally, I think that you have a lot of diversity in terms of your draw and that isn't necessarily great. You would generally want consistency above all so I would recommend dropping your two Trailblaze and then add any two of Levitate, Herald's Song, or Wisdom of the Elders. The first two since they are at 1 and 2 cost respectively might be the better option in terms of getting your low cost draw in and I think that having Levitate makes for a really good combat trick as well. I'm sure you are aware but a great combat trick is Levitate -> Bring Down. Additionally another Herald's Song allows you more card draw/discard.
Oh and you should definitely include some merchants so that you can chuck cards you don't need. Namely you will likely want to pitch extra copies of Rolant's Memorial as you might just want two copies out instead of the full 3. Really it just helps you by having a market so that you can combat other problem decks. I would recommend using Jennev Merchant since she has aegis and so if you buff her with Rolant's Memorial it is harder for your opponent to get rid of.
Just some thoughts to try out, I hope this helps!
