Passed the trials on the first try, used Vengeance Blood. Great deck, it's been significantly more effective than Mice lately.
My stats:
Forest - 98 lvl, 117 wins
Sword - 119 lvl, 220 wins
Rune - 87 lvl, 97 wins
Dragon - 119 lvl, 172 wins
Shadow - 114 lvl, 159 wins
Blood - 116 lvl, 194 wins
Haven - 119 lvl, 209 wins
Funny thing — when I realized I wouldn't be interested in playing mostly Necro anymore, I decided to level up other classes just for a change of pace so I wouldn't get bored of it too quickly. Great logic, right? I think it was already a kind of expression of fatigue from my favorite deck. It became a turning point; I seriously got into other classes, and my interest in the game grew because of it. I found other favorite decks with better win rates, hence the spread of wins. Maybe I would've reached Master faster if I'd focused more on climbing instead of experimenting with everything, but that's what I wanted, and it was definitely worth it.
The biggest revelations for me were Haven and Dragon. I love playing strong followers and controlling the board, so Aegis became the perfect control deck for me. It's a shame that in the current meta, the only Haven deck worth running is Storm, unless you want an auto-loss against every D-Shift you come across. But I like Storm Haven too, and it fits the leader. I bought Garuda just so I wouldn't have to play as Eris, who annoyed me, and frankly, I never imagined I'd actually grow to like that feathered face as a leader, lol.
Dragon appealed to me for the same reasons, and given the class mechanics, there was plenty of room to maneuver. I got lucky pulling some great legendaries for Dragon, and that was the start — I gave up trying to squeeze out wins with Discard, even though I'd leveled it up pretty well by then, and invested a ton of vials into a good deck for this class. Never regretted it; playing Dragon is almost the most fun of all.
I have the most wins with Sword, mainly thanks to an aggro build with Frog during the VD, which, funny enough, was the first meta deck I created for this class (the last class I brought up to meta standards, but it turned out to be the most effective). Before that, I was running some homemade nonsense that surprisingly yielded decent results until it became completely outdated.
Overall, I'm happy with my path to the Master rank. I got a ton of excitement and enjoyment out of it. Many thanks to Revan for popularizing this game here back in the day; I probably wouldn't have found out about it otherwise or gotten interested.
And here's one last thing — check out this beauty I found in my screenshot folder. This screenshot was taken a long time ago; I wanted to post it but completely forgot about it.

Ever since I built the deck, I dreamed of bringing them all out in a single battle, and one day it actually happened! I was up against a Sword player, and I risked getting hit by Albert from topdeck (the opponent was obviously waiting for that), but I just couldn't pass up such an opportunity.
I only managed to pull that off once, and it's the only one because once Snow White came out, there was no need to run three Aegises in the deck.
