Build: All on attack, high-crit, damage bonus, AOE and ability block
Leader:Darth Sidious, well for obvious reasons. Healing immunity, gains health upon enemy defeat.
Poggle the Lesser: Grants all allies 150% damage for 2turns and have almost same possibility to stun a character like Dooku. Grants droid allies faster time
HK-47: Ability block&AOE, have the potential to self revive
IG-88: AOE with ability block, gains crit percentage per negative status enemy hero is suffering.
Bobba Fett: Ability block AOE, self revive, grants all allies 30% crit damage (if leader).
I would like people to add comment and criticise, also I'd like to know what people's dream team is, I belive that this team will do well, as it can rush down opponent's team with multiple AOE with ability block.
