First off I’d encourage you to try and provide SOME variety in defence… At least sometimes… GTV or JTV is very monotonous in raiding already…
If you HAVE to to that route then your “best” option would probably be:
Seshat & Poseidon
Seshat cause she’s just amazing & makes her own minions… With Telluria it becomes minion overload.
Poseidon has less direct damage than Joon BUT he’s fighter class which is better for a winger than joons monk class. Additionally, Poseidon has that pesky mana protection buff which can derail some attack squads which feature/ rely on mana control cough Onatel or Telluria cough
