You mainly want to play around your 2 different summoning conditions, Tri-Brigade Graveyard plays and Harpie field flooding plays
Your main combo starter in this deck is Harpie Channeler, While at the time I am posting this Harpie Pet Dragon - Fearsome Fire Blast is not out yet, that is the card you want to go into, from there you can use them to Overlay into Dracossack and use its token ability to make it indestructible and create Zeus, this is only one of the basic plays this deck can make, If you want you can also add in Dragoon with Link spiders to go into from the tokens which then becomes Predaplant Verte Anaconda, I really suggest trying to explore this decks combos as it has more than what you usually get from Tri-brigade decks
