Interesting team! I would not have expected it to do as well as you did. Geartyrant with no sleep/stun control falls flat in my own experience. I would count Spectrefox (s) and Vigziarid as wasted slots because there are plenty of monsters which offer a lot more. I guess what pulls through for you is Dolphoone/Onigeist, then Tortogeist+Aurodragon and the Chronotitan+Geartyrant combo. Or perhaps your three ways to get an enemy monster (Horrorclaw, Tortogeist and Angelion) often give you the tools you need to win a battle.
Did you fire off DSA from Onigeist at the beginning of each battle? I’m wondering because I would’ve thought that would overlap too much with Dolphoone’s revenge. Spectrefox I can imagine you often used soul exchange on? Was there any particular section of your team that killed a lot of the enemy team very well? My gut says it was Shivadragon + Chronotitan more than anything else. How well did Vinegazer do at the back?
Mythic (Carmilla) is an exceptional mix of being ridiculously tanky as well as doing efficient sweeping that’s got practically no restriction. DR to top it all off is a bit silly… it seems overpowered and very generically good so we’ll probably see it used a lot.
Legendary (Shikabloom) is not tricky to get going at all. It wants to be used with beasts, but there are loads of good ones that exist. Union sneak attack one-shots basically everything and you can always get a second kill with protector conversion (plus set up union sneak attack again) if you don’t have beasts around when it gets another turn. If things really fall apart, it can remove itself with protector conversion. It’s a very hard to kill sweeper that is a big reward for building around it properly.
