I invade using a low-rarity team inspired by a guide here on this site. Goblin Rocket - A Guide for Invading
Pridelands banner (+2 red)
Boar Rider
Alchemist (2 traits) (+1 red)
Goblin Rocket (1 trait) (+1 red)
Goblin Rocket (1 trait) (+1 red)
Once I get 10 red for Alchemist it’s usually infinite turns, unless I make a mistake, or get really unlucky with few yellows.
Sure, I’m pretty low level, so I haven’t met these crazy defences, but I can’t imagine losing to anything with this team. Plus! It’s fun and challenging to play
