Ive been trying to playtest a kinda sneaky siege deck I made this this week. Siege engines and scenario are definitely not as strong of a finisher as vissegard uprising combo but this is a fun and fairly consistent try at one.

The idea is I try to Mulligan away cards that would obviously give the deck away as a seige engine deck round one like trebuchets. I try to win the round with bronze engines like the siege boats or boost package with anna. I usually bleed rd 2 bc you need optimally a short - medium length round 3 for siege to take it. The powercreep is pretty rough and siege doesnt make much of a dent in a long round.
