3rd account with 3rd e-mail address (this should explain weird username) finally got confirmation e-mail. I'd like to thank Double for his help, this is my replay (same he posted for me 3 posts above) from my account this time:
https://alteil-login.gamepotusa.com/aud ... 0e0a29c84eMe: Volcano prebuilt with minor set 11 modifications (Lame Emperor / Riviera instead of OPOP RMFG / Jerry, ironically there was no good moment to play her; and Song for a hero - first grim that got grimbaned). RP: 1514/1852.
Opponent: Golden star dolls, RP: 1843/1967 (his current RP was only 9 less than my all time best!).
The game: I lost 15 SP (that's not a typo!; combination of drain/return from druid ss), generated 6 SP, net loss: 9 SP. 5 of my grimuars were banned, 3 played.
SPOILER
And yet I won.
SPOILER
Try beating
that.
Short version: turn 4. I won that contest right there.

Boring analysis/rant that's not part of submission: this replay debunks few myths, most important being that SP wins you games. As you can see no, it doesn't. Opponent had 9 SP advantage, but I had raw damage. And this is why I always called Serpent/Bog Wyvern/Sorcerer Monk OP. Because you win games by killing opponent's cards, not by amassing huge amount of SP. Another myth is high RP = skill. Skilled player wouldn't iczer into Antilla ss, taking Mitzett into face was, in that situation, much better than risking revive ss. Not to mention that killing his engaged unit with my Lapierre SS was huge warning sign screaming "I want you to iczer!!!1!!". High RP has always meant one thing, and one thing only: you have a lot of free time and you spend it playing one of few unoriginal decks over and over again. All fun/new/interesting decks are at 1600- RP, give or take.
Special mention goes to my all-time favourite, Gaia Anaconda. One of most underrated cards ever, with art that cracks me up every time I play it. This card was key to my success: it allows me to play level 4 unit before Dryad Soldier SS triggers, it generates SP, it can hit even last row, it prevents early iczering, it can kill weak units forcing opponent to spend sp on revive/trigger SS early and, thanks to 2 copies, I can control when I want to sacrifice it to trigger my own SS. She basically does everything EX: Merc Girl does and then some. When I read (long time ago) how some "pro" (as in one of them high RP, no skill players) adviced that Anaconda is probably first card you want to replace while customizing this prebuilt I facepalmed. It was amazing card then and it is amazing card now.
And that's how Equestria was made.
