I commend you on your perseverance! It definitely looked dire and you did well to convert a bad situation into a win. I’ll only comment on the first half, since by the time you put down the tank and flanks there are many paths to victory and I think the decisions matter less.
The only hero you used that I have is Evelyn, so some of my comments may be wrong, as I don’t have the same perspective as you. Generally, I would have approached this match by trying to charge Finley and then using Aegir’s buff to hit everyone. If that isn’t part of a reasonable strategy then some of my ideas are probably misguided.
~0:06 I favor making the blue match in row 4 as it starts charging the mana I want while also setting up a green match in column 2.
~0:11 This may be about playstyle: I would have made the purple match in row 4, which combos the greens in column 4. I think I see the argument for the move you made (purples in column 3), but if the idea was to suck in more green I would have rather done the blue match in column 2, which sets up a green diamond in column 4.
~0:27 I don’t like the green diamond play unless it kills the tank, which it isn’t going to. I’d prefer the blue match in column 4. Generally, while the flanks aren’t charged I avoid splashing them as much as possible. Also, I’m still trying hard to get Finley charged, especially before Jean-François fires.
~0:42 Same thing - I wouldn’t make the yellow diamond, which is likely to charge both flanks. You face a truly brutal scenario when it is the defense’s turn, as all of the offensive players fire their specials. At this point you’re sitting on 4 blue tiles of mana, and while I don’t know your troops you need only 3 or 4 more for Finley and Alice. So I would have made the blue match on row 1 or 2. That would have probably charged Drake, but you still would have had a chance to get Finley ready before JF fires.
~1:12 I’m okay with firing Kunchen here even though JF’s buff flips part of his special. You need the cleanse and heal. I’m not sure I understand why Finley then gets fired. Since I don’t have him I don’t really know how much damage he inflicts in this scenario (against the defensive buff). With the heal in it feels like holding him may have been better.
~1:22 I don’t understand the green diamond. If you wanted to charge Alberich I think the green match in row 4 was probably sufficient. I also would have considered making a blue dragon in column 5. Above all, I really want to NOT splash the flanks.
~1:29 I again dislike the diamond play. I would have made the reds in row 3, which combos the blues in columnd 5. I just don’t think the purple diamond accomplishes enough in terms of the trade: mana gained by offense and damage inflicted on defense plus desired board movement vs. mana gained by defense.
~1:39 I agree we should make the blue diamond. I would have moved red D4 to D3 as it clears more tiles.
~2:19 Alberich revived Evelyn and it would have been nice to fire her before Alice.
If this video is representative I’d say you generally play faster than I prefer. There were several times when I felt you were a bit too quick to use your diamonds and specials. Possibly an even bigger difference in playstyle is that I’m very stingy about splashing the flanks, especially with a passive tank. I feel the best way to exploit the non-offensive threat is to limit the mana to the rest of the team while hoarding mine.
