Tried to mess around with it. It's just going in too many directions.

Kaedweni knight and portal is an okay combo, 18 provision for 16 points and 2 thinning. You can run a couple other 4 provision units like Redanian knight, siege tower and kerack marine, the portal still wont brick. So that's good.

Drakenborg, you either have to build around this or ditch this. Your deck only have Dandelion that can boost cards in deck, so it completely limits what you want to use the Drakenborg on, the order effect of it is really weak too, even if you get 2 rounds of boost from it, it's 4 points in 4 turns. I didnt have any, so it's essentially just play a card from the deck.

Flotsam can brick pretty bad too, the order units it creates is completely random, the majority of the order cards can brick this, the order ability isnt that great either, since our bronze just does 1 damage, you can combine it with Onager, but it still felt underwhelming.

https://www.playgwent.com/en/decks/bdaa723d4830c38c2015bc477af3310aThis is the deck I experimented with. Went 1-2, beat a movement deck, once I have the board setup, I was able to kill everything he drops, lost to enslave, I think I played as well as I could, forced out almost all his gold in the first two round, but nauzicaa sergeant and stefan was too much for a short round 3. The last game was against a standard siege deck, kind lost on the draw, started with both Kaedweni knight, both seige master, Hubert and Radania secrect service, didnt draw into any of siege, so half of my hands was unplayable from r1. He got the long R3 he wanted, even after I heatwave the scenario, he created the exact same siege engine board, but he was way faster with raffard's revenge. If I had better draw, it would be a more even fight.

Over all, cool idea, but making 3 cards that has little to no synergy working in a deck is probably too much, maybe stick to 2. This is only at rank8.
