This team is a result of wanting to have all status effects active at once on an enemy troop. Unfortunately, that doesn’t include Hunter’s mark. The only feasible way to include marked was to use Chimera for both poison and entangle, which I don’t like that his attack isn’t targetable or first troop.
Instead, I went for troops that effect all enemies. With the exception of entangle, which is only useful on the first troop. The toughest choice was Webspinner or Shadow Dragon. I didn’t like how Shadow Dragon wiped yellows, as TSO and Dimetraxia both require them. Also, True damage didn’t seem to fit well with Burn as well as damage from Dimetraxia and Swamplash. I like the damage to all on Webspinner better, and the green generation helps feed Swamplash. The only downside is lack of purple.
Webspinner and TSO are both mostly fire and forget troops. Since poison is permanent, and TSO silences himself, they are both expendable after they cast. The most focus needs to be on Dimetraxia, who only has a 25% chance to cause burn. As enemies start to die, Swamplash becomes important to recast entangle on the next troop in line.
Bonus: Because I wouldn’t feel right not ending with a full Impervious team.
